Q: Is it a sin to call a priest by his first name (not to his face but when referring to him)? I know a priest friend well and tend to call him by his first name when referring to him. — Mariana
Answered by Fr. Edward McIlmail, LC:
A: It’s not prohibited to refer to a priest by his first name. Lots of priests (though not all) refer to each other by their first names.
That said, you might want to be careful not to give any faulty impression.
Calling someone by his first name usually indicates a degree of familiarity with the person.
This isn’t necessarily a bad thing.
But for the sake of someone who has promised to live as a celibate, it’s good that you maintain a healthy emotional distance from him.
I hope this helps.
