OK, the second half of that title is fake. But apparently the first half is not.
I tend to get angry when I hear clergy say “who is to say what is a sin and what isn’t?” Why you are, Dipshit.
Imagine St Paul writing the Corinthians: “Golly gee, a man is sleeping with his father’s wife, maybe it is OK, who am I to judge?” But the confusion on the part of members of the clergy does have a reason behind it: they are confusing two roles that a pastor has with regard to the faithful, and two ways to handle moral questions.
A pastor must remind people the difference between good and evil because people like to intentionally forget. But he also must help people who have problems of conscience. Therefore a pastor must say, publicly and unequivocally, that manipulating teenagers into sex is a sin, utterly contrary to the spirit of the Gospel, and people who do it are placing themselves in danger of hell.
But if he is privately counseling a person who is tempted by this sin, or who has committed it, he must take into account that the individual’s knowledge and freedom may be impaired by his culture, his psychology, or his upbringing. These factors limit the person’s subjective culpability. A person may feel wracked with feelings of guilt for a sin he had committed, when in reality he is not as guilty as he thinks he is. Or the person may excuse his own behavior when in reality he is quite guilty. It is part of a pastor’s role to point that out.
If clergy confuse the two roles of public preaching and private counseling all they do is create confusion. They either fail to educate people about what constitutes evil acts, or they fail to guide people in their concrete life situations.
Most Catholic clergy who make this error were educated by Jesuits, who really should keep to teaching math and stop teaching moral theology.
