How well do you know the doctrine of the Trinity? Could you explain, from the Scriptures, that Jesus was God? Could you explain how the Christian understanding of Christ as God doesn’t make us tri-thiests, or people who believe in three Gods?
Watch the video below, a short five minute clip from a Unitarian who believes Jesus was a created being, and not a person of the Godhead. This video is heresy! Could you answer his argument? After the video, see a short explanation on the historical development of the orthodox doctrine of the Trinity!
What you just watched was heresy. Now, I’ll give a short account of how the orthodox Trinitarian doctrine developed:
How the Doctrine of the Trinity Developed
When you consider “how the teaching of the Trinity developed,” it is important to understand that we are not talking about how men made up this doctrine. We’re talking about the struggle to precisely put into words the body of faith received from Christ and His disciples. This oral tradition, or body of faith, had acted as a conduit for correct doctrine and had eventually been set down in writing at the prompting of the Holy Spirit (1 Pet 1:21). So, we’re not discussing how men made this doctrine up, but how they struggled to precisely synthesize and define a doctrine clearly taught in the Scriptures.
There are five basic phases in the historical development of the Triune God, each often overlapping with one another; the economic concept, dynamic monarchism, modalism, Arianism and orthodoxy. The very early church in general did not concern itself with deep theological reflection; therefore these various heretical doctrines generally emerged in conflict with orthodoxy in the mid to late 2nd century and early 3rd century. The church was chiefly concerned with basic survival amidst intense periods of persecution. “The process of organizing itself and propagating the faith and even the struggle for survival in a hostile world precluded much serious doctrinal reflection.”
This economic development dealt with the roles of the specific persons of the Godhead rather than the ontological development and its implications. Early church fathers who developed the economic concept include Hippolytus, Tertullian and Justin Martyr. Their conclusion was that God consists of one identical substance which is extended into three distinct manifestations.
Justin Martyr, writing in the mid 2nd century likened this to one fire kindled from another; “which is not lessened when it has kindled [another], but remains the same; and that which has been kindled by it likewise appears to exist by itself, not diminishing that from which it was kindled.”
Tertullian, writing sometime between 197-217 A.D., characterized this as a unity of substance and remarked,
Even when the ray is shot from the sun, it is still part of the parent mass; the sun will still be in the ray, because it is a ray of the sun—there is no division of substance, but merely an extension.
Tertullian went on, “the material matrix remains entire and unimpaired, though you derive from it any number of shoots possessed of its qualities.”
Tertullian actually formulated the concept of later orthodoxy, “one essence in three persons” in his attack on modalism. In his polemic on Praxeas, written no earlier than 208 A.D., he wrote again of a unity of substance which was distributed into a Trinity;
placing in their order the three Persons—the Father, the Son, and the Holy Ghost: three, however, not in condition, but in degree; not in substance, but in form; not in power, but in aspect; yet of one substance, and of one condition, and of one power, inasmuch as He is one God, from whom these degrees and forms and [l3] aspects are reckoned, under the name of the Father, and of the Son, and of the Holy Ghost.
This economic concept of the Trinity is orthodox but incomplete. Erickson lamented about a “certain vagueness” in the economic concept of the Trinity. “Any effort to come up with a more exact understanding of just what it means will prove disappointing.” 
This concept was an attempt by the early church to actually define the relationship between Christ and God. The main proponent of monarchism was Theodotus, who brought the doctrine to Rome about 190 A.D. He sought to preserve the supremacy of God the Father at the expense of God the Son. Jesus was not really God; God was simply working through Him.
Theodotus “did not deny Christ’s birth from a virgin . . . but he did deny his divinity, teaching that he was a mere man upon whom the Holy Spirit descended at the time of his baptism, in consequence of which he became the Christ, received power to fulfill his special mission and by his righteousness was raised above all other men. The descent of the Holy Spirit, however, although raising him to a very exalted position, did not make him divine.”
The concept was that Christ was elevated to an exalted position, a sort of “moral oneness” with God.
A key proof-text for this concept was 1 Cor 5:19, where Paul wrote “in Christ God was reconcilingthe world to himself.” Christ was not divine; God was simply using Christ as the means to achieve His ends. This view was condemned by the Christian community. Dionysius, the Bishop of Rome from approximately 259-263 A.D., held monarchist views. Eusebius recorded that Dionysius held, “contrary to the teaching of the Church, low and degraded views of Christ, namely, that in his nature he was a common man.” The catholic church (in the original sense of the term) moved energetically to combat this heresy, summoning Dionysius to a council to explain himself. Eusebius contemptuously referred to him as “a despoiler of the flock of Christ.” Monarchism was never a widespread movement and was a relatively isolated phenomenon.
Erickson wrote that modalism was “a genuinely unique, original and creative conception . . . a brilliant breakthrough.” It advocated the view that God was really just one person with three different names, roles or activities. Father, Son and the Holy Spirit are identical, successive revelations of the same person. Like a skilled thespian, God simply plays different roles at different times.
Tertullian, writing his treatise against Praxeas sometime after 208 A.D., observed dryly, “Praxeas did a twofold service for the devil at Rome: he drove away prophecy, and he brought in heresy.” Tertullian boldly claimed that Satan himself was working through Praxeas in his modalistic interpretation of the Trinity. “Out of this doctrine of the unity he may fabricate a heresy. He says that the Father Himself came down into the Virgin, was Himself born of her, Himself suffered, indeed was Himself Jesus Christ.” He went on to state,
So it is either the Father or the Son, and the day is not the same as the night; nor is the Father the same as the Son, in such a way that Both of them should be One, and One or the Other should be Both.
Employing a legal tactic of positing and answering modalistic objections, Tertullian continued,
Well, but “with God nothing is impossible.” True enough; who can be ignorant of it? Who also can be unaware that “the things which are impossible with men are possible with God?” The foolish things also of the world hath God chosen to confound the things which are wise.” We have read it all. Therefore, they argue, it was not difficult for God to make Himself both a Father and a Son, contrary to the condition of things among men. For a barren woman to have a child against nature was no difficulty with God; nor was it for a virgin to conceive. Of course nothing is “too hard for the Lord.
But if we choose to apply this principle so extravagantly and harshly in our capricious imaginations, we may then make out God to have done anything we please, on the ground that it was not impossible for Him to do it. We must not, however, because He is able to do all things suppose that He has actually done what He has not done.
The modalistic conception of the Trinity was indeed novel. It solved any number of problems; both the unity of the Godhead and the full deity of all three persons are perfectly preserved by it. Ultimately, however, Scripture condemned this heresy to the flames. Too many texts spoke far too explicitly of the Trinity as distinct persons for the church to accept; such as Christ’s baptism, Christ speaking of the coming of the Spirit and His prayers that were specifically addressed to the Father.
The Arians, like the modern day Jehovah’s Witnesses, went a different route. Christ, they asserted, was not equal with God or even God at all – He was a creature brought into being by God. They felt that elevating Christ to the level of God the Father was, in effect, abandoning monotheism. They went further than the monarchists by emphatically declaring Christ was no more than a mere creature. However, from the beginning the church had worshipped Christ as God! The stage was set for a divisive battle. Athanasius considered Arianism to be a “harbinger of the Antichrist” and the daughter of Satan. Summarizing their teaching, he wrote,
God was not always a Father; but once God was alone, and not yet a Father, but afterwards He became a Father. The Son was not always; for, whereas all things were made out of nothing, and all existing creatures and works were made, so the Word of God Himself was made out of nothing, and once He was not, and He was not before His origination, but He as others had an origin of creation.
The church was quite rightly concerned with condoning the worship of a mere man. Athanasius wrote against the Arian heresy with great enthusiasm, judging it to be a theology which had been “vomited forth” and was at odds with Scripture and “alien to the divine oracle.” Arians took Proverbs 8:22-23 as one of their primary proof-texts; “The Lord possessed me at the beginning of his work, the first of his acts of old. Ages ago I was set up, at the first, before the beginning of the earth.” The Arians examined texts such as this and others and concluded it may be appropriate to call Christ a god, but he was certainly not the same as God the Father. Arias himself explained,
God himself is inexpressible to all beings. He alone has none equal to him or like him, none of like glory. We call him unbegotten on account of the one who by nature is begotten; we sing his praises as without beginning because of the one who has a beginning. We worship him as eternal because of him who was born in the order of time. The one without beginning established the Son as the beginning of all creatures.
Therefore, according to Arians, Christ Himself could not even fathom God’s essence. He was a mere creature; an exalted creature, to be sure – but a creature nonetheless. Church historian Justo Gonzalez summarized by observing, “if asked to draw a line between God and creation, Arians would draw that line so as to include the Word in creation.”
The Arian heresy prompted the Council of Nicea in 325 A.D., the first ever ecumenical council of the early church. Prior to Nicea, church disputes had been settled over time with long debate culminating with an eventual consensus. After the conversion of Constantine, for the first time the authority of the state was invoked to settle a theological issue. Advocates of particular viewpoints could, for the very first time, forsake lengthy explanations of their positions in favor of simply convincing imperial authority. “Eventually, theological debate was eclipsed by political intrigue.”
Arianism began as a local conflict in Alexandria, Egypt. The Bishop of Alexandria, Alexander, was in vehement disagreement with Arias, who was one of the most famous presbyters of the city. Alexander eventually condemned Arias and removed him from all official positions in Alexandrian church. Arias, refusing to meekly fade from the scene, appealed to the common people of Alexandria and other Bishops from throughout the East for support. Arias was quite successful; people marched in the streets chanting Arian dogma and various Bishops wrote letters in support. The Eastern church was in turmoil.
Constantine, who had recently established Christianity as the state religion, resolved that he must act. He decided to call a council of Bishops from the entire empire to settle this matter, among others. Arias, not being a Bishop himself, was forbidden to attend. He counted on Eusebius of Nocomedia to present his views. Eusebius (not to be confused with the historian) resolved to simply explain the matter, certain that all opposition would fade away in light of the remorseless logic of Arianism. Eusebius’ oration did not go well.
The assertion that the Word or Son was no more than a creature, no matter how high a creature, provoked angry reactions from many of the bishops: ‘You lie!’ ‘Blasphemy!’ ‘Heresy!’ Eusebius was shouted down, and we are told his speech was snatched from his hand, torn to shreds, and trampled underfoot.
The result of this controversy, the Nicene Creed, is emphatically anti-Arian and takes great pains to emphasize the deity of Christ;
I believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible.
And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds; God of God, Light of Light, very God of very God; begotten, not made, being of one substance with the Father, by whom all things were made.
Who, for us men for our salvation, came down from heaven, and was incarnate by the Holy Spirit of the virgin Mary, and was made man; and was crucified also for us under Pontius Pilate; He suffered and was buried; and the third day He rose again, according to the Scriptures; and ascended into heaven, and sits on the right hand of the Father; and He shall come again, with glory, to judge the quick and the dead; whose kingdom shall have no end.
And I believe in the Holy Ghost, the Lord and Giver of Life; who proceeds from the Father and the Son; who with the Father and the Son together is worshipped and glorified; who spoke by the prophets.
And I believe one holy catholic and apostolic Church. I acknowledge one baptism for the remission of sins; and I look for the resurrection of the dead.
In the Nicene Creed the early church provided a clear and unambiguous affirmation of the full deity of all three persons of the Godhead, while at the same time maintaining their distinct roles in the economic Trinity.
The doctrine received further refinement at the Council of Constantinople in 381 A.D. where the common phrase “three in one” was coined; the very essence of the orthodox concept of the triunity of God. He is not triple, but three in one.

One thought on “How Well Do You Know the Trinity?”
Reblogged this on godschildren58 and commented:
Very well, I wrote the Book on it. Understanding God and His spirit, “The Spirit of the Lord” Jesus said to always to pray to God and God alone. Even Jesus prayed to God His Father in heaven. Understanding that God’s spirit dwells in the hearts and souls of them who love Him you begin to understand the Trinity.
