“Kapila, Orpheus, Pythagoras, Plato, Basilides, Marcian, Ammonius, and Plotinus, founded schools and sowed the germs of many a noble thought, and disappearing, left behind them the refulgence of demi-gods. But the three personalities of Christna, Gautama, and Jesus, appeared like true gods, each in his epoch, and bequeathed to humanity three religions built on the imperishable rock of ages. That all three, especially the Christian faith, have in time become adulterated, and the latter almost unrecognizable, is no fault of either of the noble Reformers. It is the priestly self-styled husbandman of the “Vine of the Lord” who must be held to account by future generations.
Purify the three systems of the dross of human dogmas, the pure essence remaining will be found identical. Even Paul, the great, the honest apostle, in the glow of his enthusiasm either unwittingly perverted the doctrines of Jesus, or else his writings are disfigured beyond recognition. The Talmud, the record of a people who, notwithstanding his apostasy from Judaism, yet feel compelled to acknowledge Paul’s greatness as a philosopher and religionist, says of Aher (Paul), in the Yerushalmi, that “he corrupted the work of that man”, meaning Jesus. Meanwhile, before this smelting is completed by honest science and future generations, let us glance at the present aspect of the legendary three religions.”
