Why would anyone trust eternal salvation to the leading of a man to whom the Way of Truth was an admitted enigma? (ainigmati, I Cor. 13:12)

For two millennia, the most powerful mental energies of the human race have been devoted to the task of seeing more clearly through that dark glass, only to leave Christendom enshrouded ever more deeply in the darkening fog. So it is that the mystery, which only a child can understand, continues to elude the genius of man.

Yes, following Paul not only could, but does and has led and will yet lead multitudes in the way that leads to destruction.  I should know, having dedicated years to misleading others in that way.  Yet the Father's mercy transcends all so that even such a one as I has hope of eternal life because there is finally only one thing that can prevent one's entrance into the Eternal Blessedness -- hanging onto life in this world and therefore not wanting to go to our Father.  It works for the Prodigal Son; it will work for you.

The Christian views on the qualifications for salvation that hinge on membership in the right church, faith in a vicarious blood sacrifice to cover sins or similar schemes do not save anyone and have never saved anyone for eternal salvation.  This is no excuse for anyone in these days when the gospels are readily available to everyone such that we can easily learn what Jesus revealed as the Way of Salvation.  

Matt.18

[3] Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven.
