Every one of them is gone back: they are altogether become filthy; [there is] none that doeth good, no, not one. – Psalms 53:3
But we are all as an unclean [thing], and all our righteousnesses [are] as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away. – Isaiah 64:6
As it is written, There is none righteous, no, not one: There is none that understandeth, there is none that seeketh after God. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one. – Romans 3:10-12
He it is, who coming after me is preferred before me, whose shoe's latchet I am not worthy to unloose. – John 1:27
About the alleged sinlessness of John the Babdiss (Local pronunciation - the 't' is silent)(hereinafter "J the B"):
Actually, to get all technical, the contention is not that J the B was without sin his entire life. It’s that, since he gave his life to Jesus at the Visitation, we, or some of us, believe that before he was BORN (but after he was conceived - therefore NOT all his life) grace began to dominate his life.
So he was not conceived w/o sin, but he was, the contention is, born in a state of grace. I don’t think this is de fide, but I could be wrong.
As for “to God be glory, not man”: if that is meant as a criticism of the doctrine of the Immaculate Conception or of this claim about J the B, I’m astonished. You know, or should know, that we think these things are entirely by God’s power and grace, and not man’s doing at all. It’s not, in the first consideration, that Mary and J the B are such swell people. It’s that God is a remarkably and always surprisingly swell (to use the theological term) God, and they are recipients of remarkably swell gifts. That Mary and J the B are swell afterwards is God’s doing.
And that’s why on “their” days, we don’t have services "to" them, but praise and thank God for His mighty acts.
