We have a bi-monthly theology class with interested folks from my congregation. Right now, we’re considering the doctrine of sin. This might seem dry as dust, but it’s not. If you read the notes, below, perhaps you’ll see why. I’ve included short-ish excerpts from the teaching session if you want the Cliff Notes version in the meantime!
Kind of a big deal …
This question “what is sin” answers one of the “big questions” of life. Everybody has these big questions, and they’re usually variations on these five:
- Origins: How did we get here? How did the world get here? What are we as human beings? How can we be sure we know anything about reality at all? What’s the purpose of life? Is there a Creator and Sustainer, or is life just random chance and accident?
- Suffering: What’s wrong with the world and with us? What are good and evil? Who defines these terms? Why does the world hurt people? Why do we hurt each other? What happens when we die? Why do we die?
- Hope: Is there a solution to suffering? Will there be justice? What is justice? What basis do we have to look forward to some “better day?”
- Rescue: How is this hope, whatever it is, achieved? What are its effects? Does it bring justice? Is this redemption individual, corporate, or both?
- The End: How will everything end? What will it be like? When will it happen? What will happen?
So, this isn’t an academic consideration—it shapes and defines how we understand the world, ourselves and God in many ways:
- God: If sin isn’t so serious, then we’ll tend to think of God as the smiling, perhaps senile grandfather. He’s indulgent. He forgives. He forgets. But, if sin is indeed quite serious, then we’re more likely to see God as pure, righteous, and holy.
- Ourselves: If sin is a matter of grading on a curve, then “goodness” is about how we compare ourselves to each other. We aren’t so bad, after all! None of us is Ted Bundy! But, if there is no curve, but a moral standard set by God, then we’re supposed to reflect God’s image and are held to His standard. This means we’re all in serious trouble.
- Salvation: What we think about sin shapes how much “trouble” we’re in. If we’re basically good, then we don’t need much supernatural intervention. Maybe just a push, now and then. But, if we’re criminals without hope, then we do need a divine intervention!
- The Church: What we think about sin shapes what we think the Church is here to do. If we’re basically “good people” in our natural state, then the Church exists to be positive, to be caring, to show love via mercy ministries (e.g. In His Steps). But, if we do need that divine intervention, then the Church is here to show and tell the Gospel and bridge-build towards the Gospel as we interact with our communities.
- Society: What we think about sin shapes how we understand politics, and our society. If we’re basically good, then we solve problems in our world by fixing unwholesome environments. If we need a divine intervention, then we see that nothing will really be solved until people’s hearts are changed by the Gospel. The ultimate hope is then in Jesus’ second coming and His establishment of the new community.
What is sin?
I’ll start with a brief survey of how some folks in the Church have answered that question.
The text we’re using for theology class, Wayne Grudem’s Systematic Theology, offers this: “sin is any failure to conform to the moral law of God in act, attitude, or nature.” This is a standard definition, no doubt derived from the 1647 Westminster Confession of Faith. Notice that Grudem captures three categories; actions, thoughts, and nature.
Here’s the Belgic Confession, Art. 15:
We believe that, through the disobedience of Adam, original sin is extended to all mankind; which is a corruption of the whole nature, and an hereditary disease, wherewith infants themselves are infected even in their mother’s womb, and which produceth in man all sorts of sin, being in him as a root thereof; and therefore is so vile and abominable in the sight of God that it is sufficient to condemn all mankind. Nor is it by any means abolished or done away by baptism; since sin always issues forth from this woeful source, as water from a fountain: notwithstanding it is not imputed to the children of God unto condemnation, but by his grace and mercy is forgiven them. Not that they should rest securely in sin, but that a sense of this corruption should make believers often to sigh, desiring to be delivered from this body of death.”
Note the emphasis on sin as a status, an infection that has spread to all people.
Here is the Church of England’s 39 Articles, Art. 9:
Original Sin standeth not in the following of Adam, (as the Pelagians do vainly talk;) but it is the fault and corruption of the Nature of every man, that naturally is ingendered of the offspring of Adam; whereby man is very far gone from original righteousness, and is of his own nature inclined to evil, so that the flesh lusteth always contrary to the spirit; and therefore in every person born into this world, it deserveth God’s wrath and damnation. And this infection of nature doth remain, yea in them that are regenerated; whereby the lust of the flesh, called in the Greek, “Phronema Sarkos”, which some do expound the wisdom, some sensuality, some the affection, some the desire, of the flesh, is not subject to the Law of God. And although there is no condemnation for them that believe and are baptized, yet the Apostle doth confess, that concupiscence and lust hath of itself the nature of sin.
Now, we turn to the 1647 Westminster Confession of Faith, Art. 6, which explains sin is a “corruption of nature” (6.5):
By this sin they fell from their original righteousness and communion with God, and so became dead in sin, and wholly defiled in all the faculties and parts of soul and body. They being the root of all mankind, the guilt of this sin was imputed, and the same death in sin and corrupted nature conveyed to all their posterity descending from them by ordinary generation (6.2-3).
Finally, we have the Lutherans in the Augsburg Confession (1630), Art. 2:
… since the fall of Adam all men who are born according to the course of nature are conceived and born in sin. That is, all men are full of evil lust and inclinations from their mother’s wombs and are unable by nature to have true fear of God and true faith in God. Moreover, this inborn sickness and hereditary sin is truly sin [that is, there is actual individual guilt] and condemns to the eternal wrath of God all those who are not born again through Baptism and the Holy Spirit.”
Sin is actually three different things at the same time, like layers of the same onion. We’ll go from the most obvious example of sin to its most fundamental essence:
Sin as lawlessness
Sin is lawlessness (1 Jn 3:4)—failing to follow God’s laws. It means breaking God’s law by what you do or don’t do; e.g. “thou shalt not kill” (Ex 20:13) and “If you really fulfill the royal law according to the Scripture, ‘You shall love your neighbor as yourself,’ you are doing well” (Jas 2:8-9). It also means breaking God’s law by what you think; Mt 5:27-28: “You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.”
Sin as a controlling disease
But, as the survey of various confessions makes clear, sin is also a disease that owns, controls, and shapes people—“it infects our personal ‘control center’” and produces “guilt and pollution.” One excellent controlling passage is Romans 6:1 – 7:6, which you can read through and note at your leisure.
This means that, as a hereditary disease, sin controls us. We’re its slaves, and it corrupts all our affections. It’s a “total act” that involves all of our beings, because it springs from the heart (Prov 4:23; Mt 12:33-37). “The heart of man is evil … It is the Headquarters of the General Staff, not the office of some lesser official … the whole man rebels against God, ego totus, and in this rebellion all the individual powers of his body-mind economy are mobilized.”
It’s shape comes from our environmental and social nexus and is always evolving, mutating, expanding, shape-shifting—it can be “baked in” even to the level of the structural fabrics of our society (e.g. racism, sexism, ethnocentrism, classism, ageism, religious hatred, ecological pollution, genocide).
Indeed, experience shows is daily how evil ‘infects’ society, spreading from one person to another, and perhaps involving them in it against their will. The power of the ‘infection’ is as great in the moral sphere as it is in physical epidemics. We ought to be aware of the fact—and remind others of it—that evil spreads to institutions and conditions, ‘infects’ them, and then breeds further evil, which, in turn, ‘re-infects’ the lives of human beings as individuals. Further, it is evident that the evil which is incorporated in asocial institutions, and the evil which becomes a mass phenomenon, waxes great and assumes demonic forms, which, as a rule, are not found in any individual evil. Evil which takes the shape of social wrong, or is incorporated in institutions, or as a mass phenomenon, is worse than evil in any individual form, in isolation.”
All this is why we must be “born again” (Jn 3:5-7), because we need a new mind and new heart (cf. Ezek 36:25-26)—the Spirit must “wash” us clean (Titus 3:5) and “cleanse” us from this disease. Union with Christ (pictured by the object lesson of believer’s baptism) breaks that metaphysical slavery and sets us free.
We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his.Romans 6:4-5
Sin as cheating on God and rejecting His community
Largely following Stanley Grenz, with an assist from Emil Brunner and Millard Erickson, I believe the most basic essence of sin is infidelity to God and His plan for community. Other suggestions are (1) rebellion and apostasy, (2) selfishness, (3) a privation or absence of goodness, or (4) displacement of God. These are good options. Still, infidelity and rejection of community seem to strike at the heart of “sin.”
God made us to be in community with Him and each other. By sinning, our first parents rejected His community (just as Satan had done), and so God had to expel them from Paradise (“he drove out the man,” Gen 3:24).
The bible’s story is God choosing and rescuing a community for His kingdom—we’ll only have peace and purpose in our lives when that relationship is fixed by pledging allegiance to Jesus. Sin is the great “problem” that stands in the way; lawlessness caused by a controlling force that has ruined our hearts and minds.
This isn’t an impersonal, legal crime, but a personal attack and rejection—infidelity, adultery (cf. Hosea 1-3), a hurtful treachery (Hos 6:7; Isa 48:8; Jer 3:1-2, 8-10, 20, 5:11; Ezek 16:15f). There’s a reason why God so often frame this treachery as “adultery.” It’s the ultimate betrayal, the most personal and hurtful betrayal imaginable. It’s why God chose to use it when He expressed His anger.
So, “sin” is fundamentally about saying “no” to God’s community; “cheating on Him” and thus destroying our relationship with Him (fear of Him; Gen 3:10), with each other (Gen 3:7, 16), and with the natural environment God gave us (Gen 3:17-19)—the world God gave us is no longer our friend.
For fun, I’ll also throw in a video of the free-ranging discussion we began during our last class on the question “why did God allow Adam and Eve to sin? This is one of the trickiest questions of the Christian faith. It all comes down to providence, and HOW God controls this world. In this video, the other pastor in my congregation lays out some options, we look at scripture, and then have a free-ranging discussion about the topic. If you want to know the answer to this question, read Article 13 from the 1619 Belgic Confession of Faith:
We believe that the same God, after he had created all things, did not forsake them, or give them up to fortune or chance, but that he rules and governs them, according to his holy will, so that nothing happens in this world without his appointment; nevertheless, God neither is the author of, nor can be charged with, the sins which are committed.
For his power and goodness are so great and incomprehensible, that he orders and executes his work in the most excellent and just manner even when the devil and wicked men act unjustly. And as to what he doth surpassing human understanding we will not curiously inquire into it further than our capacity will admit of; but with the greatest humility and reverence adore the righteous judgments of God which are hid from us, contenting ourselves that we are disciples of Christ, to learn only those things which he has revealed to us in his Word without transgressing these limits.
This doctrine affords us unspeakable consolation, since we are taught thereby that nothing can befall us by chance, but by the direction of our most gracious and heavenly Father, who watches over us with a paternal care, keeping all creatures so under his power that not a hair of our head (for they are all numbered), nor a sparrow, can fall to the ground, without the will of our Father, in whom we do entirely trust; being persuaded that he so restrains the devil and all our enemies that, without his will and permission, they can not hurt us.
Here is our free-flowing discussion on the topic. Next time, we’ll narrow things down and see what the Church has taught and believed about this difficult subject.

 “The sinful destruction of community has been the human predicament from the beginning. The transgression of our first parents led to the unmistakable disruption of community. Their act brought alienation or estrangement where once had been only fellowship. The innocent transparency in the presence of each other they had once known gave way to shame (Gen 3:7). In addition, Adam and Eve now feared the face of God who had lovingly created them (v. 10). And they now experience the bitter reality that the world around them was no longer their friend (vv. 15, 17, 19),” (Grenz, Theology, p. 188).
