I know I may be preaching to the choir, but the following reasoning might assist those who do not understand the discernment involved.
Which has more authority?
A man wearing traditional garb, insisting we call him Father, and given such a title by Tradition within the RCC?
OR
The Word of God instructing us not to call another man Father?
If the later, then how can one place any veracity in the volition of the former?
If the former, then he has now become the counterfeit substitute for what God has provided in a direct relationship with God the Father via His Son.
Unlike any other time before the Incarnation, believers today have the power given them by God the Father to have a direct relationship with Him.
The ONLY intermediary is God the Son. Any other intermediary becomes a counterfeit substitute for Christ. What has that counterfeit substitute provided which not only exceeds that of the Son, but is even recognized by God the Father as senior to that which He has given the Son?
None
Mat 23:9
(9) And call no man your father upon the earth: for one is your Father, which is in heaven.
