Does any church denomination believe it possible to go one moment without sinning?

No I don't think it is possible.

All our actions even the best ones are always motivated by some form of selfishness.

Take motherly love for example. A mother's love may be based in a lot of factors one of which may be a need for old age security. (emphasis on maybe) That could be why a mother has the strongest love for her own children and not for other children roaming in the street.

We could go on from there to all of our other relationships. We make friends that laugh at our jokes and like the same movies. We try to date that guy (or gal) that looks smart and is intelligent. And then we try to marry a guy who is rich, dumb and altogether silent.

In each of the cases we expect something for ourself.

Even when we may do something at a complete loss, we have at the back of our head an unconscious idea that we won't admit even to ourselves. "I did this, I must be a very good person." "Psalms says one who gives to poor lends to Lord, so God must be pleased." Or hundreds of different variations thereof.

Now compare this to God. Who does he have to please? What does he stand to gain out of anything? His love is kind of like quantum mechanics. When you hear about it you nod approvingly with absolutely no idea what it's all about.

And human nature is kind of like Chemistry. You have few basic elements which can be combined to create an uncountable number of compounds. But all of those different from each other, and just by looking at the them you can't always guess the constituents.

The corruption/original sin forms the fundamental element of human nature. Whenever we cook up a thought or action it always finds its way into it some way or other. It may not be directly visible (just as you couldn't tell that water contains hydrogen just by looking at it), but it's always there.

Everything in our life is laced with trace quantities of pride and self love. Our hope and faith in God are laced with a desire to roll around the clouds and send bolts of lightning at will.

I could ramble on with examples but this my point - I don't think it is possible to achieve the purity of thoughts at the same level as God for even a single moment. Purity and love are defined by what God is/does. And we can't be God.

A better part of our eternity in heaven would be spent in trying to become like Him, and to try to imitate (desperately and hopelessly) the one who -

Job 4:18 ... puts no trust even in His servants; And against His angels He charges error.

Let us look at 1 John 1 "5 This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. 6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: 7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make him a liar, and his word is not in us."

Yet, let us also look at 1 John 2 "1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: 2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world. 3 And hereby we do know that we know him, if we keep his commandments. 4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him. 5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him. 6 He that saith he abideth in him ought himself also so to walk, even as he walked."

Of course, nothing holds true for what all Baptists believe, but according to the theology taught in our Church, there is a distinction between what we are and what we do, or at least, what we currently are doing.

It is upon that distinction that this question can be answered.

From our understanding of the doctrine of original sin, it teaches that we are sinners from conception on. It does not teach that we sin each and every moment of our life, but rather that we are, by nature, sinners.

From http://sbcheritage.com/baptist-statesman-james-boyce-on-original-sin-and-imputed-guilt/

6. The Scriptures plainly assume and declare that God righteously punishes all men, not only for what they do, but for what they are. Men are indeed represented as more guilty and sinful than they know themselves to be, because, through the restraints with which God surrounds them, their natures have not been fully developed into all the sin towards which they tend. This is the argument of the first part of the Epistle to the Romans, the turning point of which is Romans 2:1. It is also illustrated in the case of Hazael. 2 Kings 8:12, 113.

7. It follows from the facts in these last two statements, that a corrupt nature makes a condition as truly sinful and guilty, and liable to punishment, as actual transgressions. Consequently, at the very moment of the birth, the presence and possession of such a nature shows that even the infant sons of Adam are born under all the penalties which befell their ancestor in the day of his sin. Actual transgression subsequently adds new guilt to guilt already existing, but does not substitute a state of guilt for one of innocence. [Emphasis Added]

Preface: This is from a denomination that believes that you cannot lose your salvation once saved.

As believers, we are justified, redeemed, and no longer guilty of sin. However, we do, as saved believers, still commit sins. It's just that those sins are also covered by the blood of Christ. (I'm going to stop there because it's really easy to go off on a tangent here.)

Similarly, these are fast airplanes.

But at the moment this picture was taken, they were not going fast. The fact that they are not going fast does not change their nature, or negate the fact that they are fast planes.

Based on this distinction, the question, can we go a moment without sin is "yes".

Even though we are sinners from birth, and we are always sinners, until saved by Grace, that does not mean that we are constantly sinning. The fact that we may not be sinning at any given moment does not negate the fact that we are sinners.

Other comparinsons:

• A thief can go a moment without stealing, but is still a thief.
• A murderer can go a moment without killing, but is still a killer.

All of the above provides the framework for the argument that it is theoretically possible. Specifically, you asked if any Christian denomination actually thinks it's possible, and the answer is a resounding "yes". There are more than one, but here is one Church's view.

John warns that we should never think that we immune to the problem of sin. "If we say that we have no sin, we deceive ourselves, and the truth is not in us" (I John 1:8). Therefore, we must ever be vigilant against sin. "Therefore let him who thinks he stands take heed lest he fall" (I Corinthians 10:12).

However, I know of no passage that claims that a person sins daily. Instead, the Christian is told to strive to remove sin from his life.

"What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it?" (Romans 6:1-2).

"Awake to righteousness, and do not sin; for some do not have the knowledge of God. I speak this to your shame" (I Corinthians 15:34).

The goal is not to sin. If we do stumble, we have a way out.

"My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous" (I John 2:1).

But it would be false to conclude that such sins occur daily or are even necessarily frequently. The Christian is striving to become like Christ, who knew no sin. "But, speaking the truth in love, may grow up in all things into Him who is the head -- Christ" (Ephesians 4:15). We won't reach the perfection that Christ has, but we do strive to imitate him. Thus, in that growth, if we are successful, one would expect to find the occurrences of sin to become less frequent as the Christian gains skills in battling sin. "Therefore submit to God. Resist the devil and he will flee from you" (James 4:7).

Think of it this way, did Jesus give the adulterous woman an impossible task when he told her, "go and sin no more" (John 8:11)?
