There are two ways of instruction, as there are two powers, that of light and that of darkness. And there is a great difference between the two ways. One is controlled by God’s light-bearing angels, the others by the angels of Satan. And as the latter is the ruler of the present era of lawlessness, so the former is lauded from eternity to eternity. Among the precepts of the way of light is this; do not murder a child by abortion, or commit infanticide.

Epistle of Barnabas, A.D. 138
