God makes the rules - NOT YOU! If HE says it's in vain - then that's what it is. Your choice to be instructed as HE says or not.God wrote:
And I say to you: That you are Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. 19 And I will give to you the keys of the kingdom of heaven. And whatsoever you shall bind upon earth, it shall be bound also in heaven: and whatsoever you shall loose on earth, it shall be loosed also in heaven.We in the Catholic (Universal) Church given us by Jesus Christ follow His words, why don't you?
"...I have appeared unto thee for this purpose, to make thee a minister both of these things which thou has seen, and of those things in the which I will appear unto thee." (Acts 26:16).
Jesus Christ. To Paul. After He spoke to Peter.
Yet in His agony in the garden He foresaw the disobedience and pride of those as Calvin Luther and Henry who would rend asunder His one true church into the 30000+ reorganized bands of blasphemy which claim to follow His word. They have eyes but are blind ears but can't hear . No wonder His agony was so great.
