As for this one:
“Protestantism has no central authority, and no priesthood properly so-called. It has not an apostolicity such as the true Christian Church requires. “
It has the BIBLE, for heaven’s sakes.
Protestantism has our Lord and Savior Christ Jesus as the Chief Cornerstone of the Church, not the Pope. Those who call their denomination the Church, fail to exercise faith through Christ, when they place the Pope between any believer and God.
“It has the BIBLE, for heavens sakes.”
To which I expect someone to respond that we are unworthy to interpret the meaning of the Bible. that we must have a priest to translate for us.
Of course there is no biblical basis for that position.
Considering also the most recent heinous crimes for which the leaders of the Church at Rome both deny and protect the evildoers, would give me great pause to be claiming "the One True Faith" as well as the now and future "qualified" inhabitants in Heaven.
As our Lord said, "Many will say to Me in that day, 'Lord, Lord have we not prophesied in your name.....' And then I will declare to them, 'I never knew you; depart from Me, you who practice lawlessness!' Matt:6:22 & 23.
