That doctrine was man made in the 1500s and not in the Bible.William, most Catholics hate the evangelical doctrine of salvation by Grace alone through faith alone in Christ alone. It seems to be their most hated group. Many other churches also teach salvation through some vague system of works which is what the entire catholic dogma is centered on, so they feel they have more hope of converting them.
To the church a protester is a protester. The Evangelicals protest other protestants more than Jesus' church. The Church are not fond of any because they ignore the prayer of unity Jesus made. They divide Christ.
The world ignores Protestantism now because of the complete disunity among them.
So far the candidates for Presidents that in the next election are all Catholics, at least by identity, except for Hillary.
