Where do you draw the line then between temptation and sin?
Does the person have to make a firm mental resolution to commit the sin, or is it a sin consider it in a, “Perhaps I will, perhaps I won’t, Yes I think I’ll do that, no I don’t think I will. Perhaps I’m not sure whether I will do that or not. i think I might do that. Maybe I won’t.”
At what point is the line crossed?
That is the harder element to determine. There may be a mental struggle, which is normal, and one should persist in the struggle to overcome the temptation. These are some factors that may reduce our culpability:
- Emotional wounds
- Established habits
- Strong coercion
- Great fear
- Great fatigue
But, if care is not taken to avoid the near occasion of sin, it demonstrates willful neglect. Also willfully remaining ignorant increase our culpability. Near occasions are “all the persons, places and things that may easily lead us into sin”. (Baltimore Cat. A 771)

1790 A human being must always obey the certain judgment of his conscience. If he were deliberately to act against it, he would condemn himself. Yet it can happen that moral conscience remains in ignorance and makes erroneous judgments about acts to be performed or already committed.
1791 This ignorance can often be imputed to personal responsibility. This is the case when a man "takes little trouble to find out what is true and good, or when conscience is by degrees almost blinded through the habit of committing sin."59 In such cases, the person is culpable for the evil he commits.
Baltimore Catechism No. 3 has this:
Q. 284. What does “sufficient reflection and full consent of the will” mean?
A. “Sufficient reflection” means that we must know the thought, word or deed to be sinful at the time we are guilty of it; and “full consent of the will” means that we must fully and willfully yield to it.
Q. 285. What are sins committed without reflection or consent called?
A. Sins committed without reflection or consent are called material sins; that is, they would be formal or real sins if we knew their sinfulness at the time we committed them. Thus to eat flesh meat on a day of abstinence without knowing it to be a day of abstinence or without thinking of the prohibition, would be a material sin.
**Q. 772. Why are we bound to avoid occasions of sin?
**A. We are bound to avoid occasions of sin because Our Lord has said: “He who loves the danger will perish in it”; and as we are bound to avoid the loss of our souls, so we are bound to avoid the danger of their loss. The occasion is the cause of sin, and you cannot take away the evil without removing its cause.
Q. 773. Is a person who is determined to avoid the sin, but who is unwilling to give up its near occasion when it is possible to do so, rightly disposed for confession?
A. A person who is determined to avoid the sin, but who is unwilling to give up its near occasion when it is possible to do so, is not rightly disposed for confession, and he will not be absolved if he makes known to the priest the true state of his conscience.
Q. 774. How many kinds of occasions of sin are there?
A. There are four kinds of occasions of sin:
- Near occasions, through which we always fall;
- Remote occasions, through which we sometimes fall;
- Voluntary occasions or those we can avoid; and
- Involuntary occasions or those we cannot avoid. A person who lives in a near and voluntary occasion of sin need not expect forgiveness while he continues in that state.
