Where Does Heresy Come From?

Let the Church Father John Chrysostom instruct us: “Nothing is so injurious to mankind as to undervalue friendship ; and not to cultivate it with the greatest care; as nothing, on the other hand, is so beneficial, as to pursue it to the utmost of our power. This Christ has shown, where He says, “If two of you shall agree on earth, as touching anything that they shall ask, it shall be done for them of My Father” (Matt. xviii. 19.); and again, “Because iniquity shall abound, love shall wax cold.” (Matt. xxiv. 12.) It is this that has been the occasion of all heresies. For men, because they loved not their brethren, have envied those who were in high repute, and from envying, they have become eager for power, and from a love of power have introduced heresies.”
