While I practice Catholic (Italian-Irish wife would have it no other way), I will leave it up to my Lord Jesus Christ to judge me and whether I am worthy of salvation.
Which is, IMHO, the way it should be.
Luther got it right, Biblically speaking, and any Catholic or Protestant who has followed the Biblical path [articulated by Luther below] to salvation is indeed saved.
[Excerpted from Luther's Sunday after Christmas and New Year's Day sermons in Sermons of Martin Luther, edited by John Nicholas Lenker]
He who does not believe that Christ is true God is lost; witness John 8:24: "Except ye believe that I am he, ye shall die in your sins." And (Jn 1, 4): "In him was life, and the life was the light of men." And again (Jn 14,6): "I am the way, and the truth, and the life." . . .
Now, if we were not to cleave by faith unto Christ as true God, God would be robbed of the honor due him, and we of life and salvation. It is our duty to believe in God only, who is the Truth; without him we cannot live or be saved. . .
God will not make a special way for you. He will not, because of your service annul his covenant. You must abandon your own efforts and cleave to the seed he mentions, to that flesh and blood; otherwise you will be lost with all ths spiritual skill and wisdom you may have gained from God. Christ says (Jn 14,6), "No one cometh unto the Father, but by me."
It is supremely essential, therefore, to possess him who has accomplished the purchase for us. Nor is it possible to obtain grace otherwise than through him. . . .
. . .we must all come to Christ, who is made Lord over all things, and with whom is the throne of grace. He has obtained salvation for us. Consequently it is in vain to seek it elsewhere.
