Yes, we shouldn't be adding anything to the Scriptures, especially something that is a contradiction to it.
When I was a Catholic, we call our priests "Father." That's directly against the Scriptures:
Matthew 23
Woe to the Scribes and Pharisees
23 Then Jesus spoke to the multitudes and to His disciples, 2 saying: “The scribes and the Pharisees sit in Moses’ seat. 3 Therefore whatever they tell you to observe, that observe and do, but do not do according to their works; for they say, and do not do. 4 For they bind heavy burdens, hard to bear, 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 to be seen by men. They make their phylacteries broad and enlarge the borders of their garments.
6 They love the best places at feasts, the best seats in the synagogues, 7 greetings in the marketplaces, and to be called by men, ‘Rabbi, Rabbi.’ 8 But you, do not be called ‘Rabbi’; for One is your Teacher, the Christ, and you are all brethren. 9 Do not call anyone on earth your father; for One is your Father, He who is in heaven.
