6. _As to the Antiquity of the Doctrine of Transubstantiation_. As stated in the text, the date of origin of the Catholic doctrine of transubstantiation has been debated. The following summary is instructive. "Protestants combatting the Catholic idea of the real presence of the flesh and blood in the eucharist--transubstantiation-- have endeavored to prove that this doctrine was not of earlier origin than the eighth century. In this, however, the evidence is against them. Ignatius, bishop of Antioch, writing early in the second century, says of certain supposed heretics: 'They do not admit of eucharists and oblations, because they do not believe the eucharist to be the flesh of our Savior Jesus Christ, who suffered for our sins.' (Epistle of Ignatius to the Smyrneans.) So Justin Martyr, also writing in the first half of the second century: 'We do not receive them [the bread and the wine] as ordinary food or ordinary drink, but as by the word of God, Jesus Christ, our Savior, was made flesh and took upon him both flesh and blood for our salvation, so also the food which was blessed by the prayer of the word which proceeded from Him, and from which our flesh and blood, by transmutation, receive nourishment, is, we are taught, both the flesh and blood of that Jesus who was made flesh.' (Justin's Apology to Emperor Antoninus.) After Justin's time the testimony of the fathers is abundant. There can be no doubt as to the antiquity of the idea of the real presence of the body and blood of Jesus in the eucharist; but that proves--as we said of infant baptism--not that the doctrine is true, but that soon after the apostles had passed away, the simplicity of the gospel was corrupted or else entirely departed from."--(B.

Among the controlling causes leading to the general apostasy of the Church, we have specified as third in the series: _Unauthorized changes in Church organization and government_.
