The Protestant Churches have as much right to say they have the truth as the Churches of the Corinthians, Ephesians, Colossians, etc., in early times.

You are supposing that the Protestant Churches have the same doctrine, worship, and discipline as those early Churches. But this is an unwarranted supposition. Those early branch foundations of the one true Church had the true doctrine, and were in communion with St. Peter, Bishop of Rome, who addressed his first Epistle to the Galatians and several other Churches. Protestant Churches do not hold the same doctrine as those early Churches, nor do they acknowledge the same obedience. Also, in all the countries where Protestant Churches exist, there exists also the Catholic Church which corresponds exactly with the Churches of the Corinthians, Ephesians, Colossians, etc.
