How to play a weak hand

From Catholic philosopher and apologist Michael Liccione:

Generally, though, one can’t get Orthodox and conservative Protestants to agree that that’s what the Catholic Magisterium does. They still hold that the Catholic Church has “invented” doctrine because they point out, with some justice, that distinctively Catholic doctrines cannot just be logically deduced from the early sources. Unless, therefore, one antecedently accepts the claims of the Catholic Magisterium for itself, one cannot present such doctrines as binding on the faithful.
