Q. 1. I noticed that some priests have an abbreviation after their name. What does that abbreviation mean?

A. 1. Letters after the name of a priest usually means that they belong to a religious Order. Those letters identify the religious Order. Example:

O.M.I. means the "Oblates of Mary Immaculate."

C.S.P. means the "Community of St Paul."

O.P. means the "Order of Preachers."

S.J. means the "Society of Jesus."
