We are not only forbidden to use flattering religious titles in front of people’s names, but we are warned by God to beware of those who do.

Even Paul never put the word “apostle” in front of his name. Moreover, the word “reverend” occurs only once in scripture, and it’s referencing God. (What blasphemy it is for a sinful man to identify himself as “reverend”).

Psalm 111:9
“He sent redemption unto his people: he hath commanded his covenant for ever: holy and reverend is his name.”

[bishop, pastor, elder, deacon, etc are functions, not titles]

Job 32:21-22

21 “Let me not, I pray you, accept any man’s person, neither let me give flattering titles unto man.

22 For I know not to give flattering titles; in so doing my maker would soon take me away.”

Matthew 23:4-12

4 “For they bind heavy burdens and grievous to be borne, and lay them on men’s shoulders; but they themselves will not move them with one of their fingers.

5 But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments,

6 And love the uppermost rooms at feasts, and the chief seats in the synagogues,

7 And greetings in the markets, and to be called of men, Rabbi, Rabbi.

8 But be not ye called Rabbi: for one is your Master, even Christ; and all ye are brethren.

9 And call no man your father upon the earth: for one is your Father, which is in heaven.

10 Neither be ye called masters: for one is your Master, even Christ.

11 But he that is greatest among you shall be your servant.

12 And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.”
