@Kylissa - In light of your comments about how the Fathers treated thoughts of sins with confession, what makes temptation a sin? In Hebrews it speaks of Jesus being tempted in every way we are, yet He was without sin. I'm not saying you and the Church Fathers are wrong - but I am curious as to the general position of the Church overall on what makes temptation sin.
St Theophan the Recluse said that there are phases of temptation- and that it may be a sin or not be a sin depending on the stage you are at.
"Be strong. The enemy fights you.
But this does not mean that you are sinful. Nor should his attacks shake you or confuse you. Temptations arise from the envy of the enemy and return to his head. Not only you are not responsible for it, but provided you struggle you will profit from it. Each time you repulse an attack of the enemy you secure a victory and you gratify God. It is not possible to avoid the annoying attacks of the enemy. Our life is formed in such a way. But this does not lead to the loss of the fighter, but rather to his salvation. As a consequence of the fall of the first created humans the passions nestle in us."
So if we are tempted and turn away from that temptation, it is a spiritual victory. The initial temptation is a result of an attack by the enemy. We need to turn away from it immediately. Preoccupation with that sinful thought moves us closer to committing that sin. This would be a gray area. St Theophan says that at this phase, "Sin is still not occurring, but its beginning is created.". Once in the third phase, in which we take pleasure at the thought of sin, we are in an unclean position. While the actual sin has not occurred, the sin of taking pleasure at the thought of the sin has taken place. The fourth and fifth phase are the unintentional bending of will towards that sin and consenting to commit the sin. Again, these put a person into an unclean state. The sixth stage is the actual committing of the sin itself.
Perhaps we don't need to get into defining which stage of temptation we are at (I have a hard enough time figuring out exactly what to confess without analyzing whether it is or is not a sin!), but I do think it is helpful to recognize that the enemy does present temptations in front of us, and that turning away from those temptations is a spiritual victory. If we turn away immediately - I don't think it is a sin. That said, I am not 100% confident in what makes a temptation no longer just a temptation but also a sin.
Any thoughts?
