From a reader:
If one has wronged a priest, in such way as that the wrong should be confessed sacramentally, ought one
* to approach that priest, if possible before any other
* to approach some other priest at all costs
* not worry, just go to one’s usual confessor even if it was him
No, you don’t have to go to confession to him on this point. But you do have to make amends.
Also, if he is the only priest around, and the alternative would be not going to confession for a long time, then you should simply go to him for your confession.
Keep in mind that in wronging a priest, you are not simply wronging a man. You wrong a man who has sacred orders. Depending on how you wronged that priest, you may also have to confess the sin of sacrilege.
Sometimes wrongful actions are more than one sin at once. Anytime something or some place or someone consecrated is involved, you usually also are committing a sacrilegious act in harming them.
