That is the only rational argument I have heard so far for leaving the Church. I disagree with it, but it’s rational.
All I can say is this. If the leadership of any church chooses to willfully ignore their own teachings, then they themselves either do not believe them or are putting something else before God. There is no other way around that.
If a person sits in a pew being led by men who do not believe what they say or subordinate the word of God to political expedience, they are no closer to following the right path than if they wing it and go their own way.
I do not see how it can be any other way. Note that I Believe in the teachings of RC. I do NOT believe in the men teaching it and feel that they have no business trying to when they ignore it when convenient/profitable.
