Matan1:
Why not?
If you Google Rabbi JB, then you will find that “YU Torah” deems it:
“Rabbi J.B. Soloveitchik”.
The more reverential appellation is “Rav…”, which is what I used.
Would you prefer “Rabbi…” instead of “Rav…”?
Also, are you saying one should not use someone’s initials when it is clear to whom those initials refer to? Why would you write that?
