Pseudo-Clementine Literature.: Chapter III

Chapter III.—Obstacles to Faith.

And our father said:  “There is evidently much reason in what you say.”  And Peter said:  “What is it, then, that prevents you from coming to our faith?  Tell me, that we may begin our discussion with it.  For many are the hindrances.  The faithful are hindered by occupation with merchandise, or public business, or the cultivation of the soil, or cares, and such like; the unbelievers, of whom you also are one, are hindered by ideas such as that the gods, which do not exist, really exist, or that all things are subject to Genesis, or chance, 1223 or that souls are mortal, or that our doctrines are false because there is no providence.
