If they have authority given to them by God and we are submitted to the them then we should do as they say, but if they do not do not also do the right things, we are not to imitate their errors. First consider what Jesus said:
"... The scribes and the Pharisees sit in Moses' seat
All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not.
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" Matt 22:2-4
Those of which Jesus spoke had the position, but they presented poor examples. Who is it today who has positions given to them by God? We should not presume a person has it simply because he says he does. Unfortunately, men, even so called men of the cloth, the clergy, also may be liars?
"Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves
Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit." Matt 7:15-17
But then Apostle Paul also advises us to give double honor to some? To whom?
"Let the elders that rule well be counted worthy of double honour, especially they who labour in the word" I Tim 5:17
To one holding a title or position in a church group who does Not labour in the Word should Not be honored!
