The examples in the Bible are not to fawn over or worship (in any way or under any name) humans. This would extend to titles. Worship belongs to God alone. Titles such as His Holiness for any person would be repulsive to God. Do you think Jesus or the Disciples would really bend the knee and kiss the ring of the Pope and refer to him as “His Holiness”? The term “Reverend” is found in the Bible only once and it is a reference to God lest anybody think I am excluding the Protestants on this. The terms “brother” and “sister” are more appropriate.
Amen! Matthew 23 teaches this principle clearly.
23 Then Jesus said to the crowds and to his disciples, 2 “The scribes and the Pharisees sit on Moses’ seat, 3 so do and observe whatever they tell you, but not the works they do. For they preach, but do not practice. 4 They tie up heavy burdens, hard to bear, and lay them on people’s shoulders, but they themselves are not willing to move them with their finger. 5 They do all their deeds to be seen by others. For they make their phylacteries broad and their fringes long, 6 and they love the place of honor at feasts and the best seats in the synagogues 7 and greetings in the marketplaces and being called rabbi by others. 8 But you are not to be called rabbi, for you have one teacher, and you are all brothers. 9 And call no man your father on earth, for you have one Father, who is in heaven. 10 Neither be called instructors, for you have one instructor, the Christ. 11 The greatest among you shall be your servant. 12 Whoever exalts himself will be humbled, and whoever humbles himself will be exalted.
No worship here. Just a title of respect — Do you ever say, “Dearest Mother” or “Dear Grandfather”?
Same thing — just a title of respect.
