Sometimes my friends call me Father as a joke. It is funny because I am a woman and not a priest. We are wondering if this is a sin of irreverence.
This is a subjective matter.
I really think that a good joke can lift the spirit. I do not imagine the apostles living without joking. I imagine them living happily.
A joke can certainly be offensive, but there are other jokes that simply reflect an unsuspected result from a small story.
This is a question tagged with catholicism, so: I know many priests, and sometimes they joke about themselves, and no irreverence is implied or even considered, just a funny outcome.
The specific statement would hardly be a sin, but if you feel guilty, as a Catholic, just add it to your confession and be done.
Probably the other person can say that because of some kind of compliment, probably you gave a piece of good advice, probably a little critique if you are "preachy".
The definition of sin Cathecism Number 1849
Sin is an offense against reason, truth, and right conscience; it is failure in genuine love for God and neighbor caused by a perverse attachment to certain goods. It wounds the nature of man and injures human solidarity. It has been defined as "an utterance, a deed, or a desire contrary to the eternal law.
I think it's the same way the generation of Noah made fun of him while he was building the ark and the floods came and took them all away. It is a sin to make fun of a servant of God because God does not joke, 42 children made fun of Elisha the servant of God and he cursed them and a bear ate them all.
The Pharisees and the high priest made fun of Jesus while he was on the cross and darkness covered the whole land from noon to the third hour in the afternoon, a great earthquake hit the city and the curtain of the temple was torn into two.
