A true Gnostic sentiment, over against which the pious “agnosticism” of Apelles is not altogether unrefreshing. The Church did not fully conquer Gnosticism,—Gnosticism in some degree conquered the Church, and the anti-Gnostics, like Apelles, were called heretics. It was the vicious error of Gnosticism that it looked upon Christianity as knowledge, that it completely identified the two, and our existing systems of theology, some of them, testify to the fact that there are still Gnostics among us.
