If the church teaches something is a mortal sin, but I really don’t see it as a big deal especially because it only hurts me what do I when I go to confession? Just not confess this? Can I receive communion? Also the act is almost always a symptom of a mental problem and requires counseling. I do feel as if I have full responsibility but I don’t think it is as big of a deal as the church is making it out to be.
If you understand that the Church teaches that a particular sin is grave, and you freely do it anyway, then it is mortal, and you may not receive communion.
Baltimore Catechism:
Q. 280. What is mortal sin?
A. Mortal sin is a grievous offense against the law of God.
Q. 281. Why is this sin called mortal?
A. This sin is called mortal because it deprives us of spiritual life, which is sanctifying grace, and brings everlasting death and damnation on the soul.
Q. 282. How many things are necessary to make a sin mortal?
A. To make a sin mortal, three things are necessary: 1.a grievous matter, sufficient reflection, and full consent of the will.
Q. 283. What do we mean by “grievous matter” with regard to sin?
A. By “grievous matter” with regard to sin we mean that the thought, word or deed by which mortal sin is committed must be either very bad in itself or severely prohibited, and therefore sufficient to make a mortal sin if we deliberately yield to it.
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. 286. Do past material sins become real sins as soon as we discover their sinfulness?
A. Past material sins do not become real sins as soon as we discover their sinfulness, unless we again repeat them with full knowledge and consent.
Q. 287. How can we know what sins are considered mortal?
A. We can know what sins are considered mortal from Holy Scripture; from the teaching of the Church, and from the writings of the Fathers and Doctors of the Church.
