I’ve reviewed some of St. Basil today, talking about internal threats. I thought his words were pretty amazing:
Our distresses are notorious, even though we leave them untold, for now their sound has gone out into all the world. The doctrines of the Fathers are despised; apostolic traditions are set at nought; the devices of innovators are in vogue in the Churches; now men are rather contrivers of cunning systems than theologians; the wisdom of this world wins the highest prizes and has rejected the glory of the cross.—St. Basil the Great, Letter 90, to the Western Bishops
I have observed the ingenuity of the devil’s mode of warfare. When he saw that the Church increased under the persecution of enemies and flourished all the more, he changed his plan. He no longer carries on an open warfare, but lays secret snares against us, hiding his hostility under the name which they bear, in order that we may both suffer like our fathers, and, at the same time, seem not to suffer for Christ's sake, because our persecutors too bear the name of Christians.—St. Basil the Great, Letter 139
And what is our condition? Love is grown cold; the teaching of the Fathers is being laid waste; everywhere is shipwreck of the Faith; the mouths of the Faithful are silent; the people, driven from the houses of prayer, lift up their hands in the open air to their Lord which is in heaven. Our afflictions are heavy, martyrdom is nowhere to be seen, because those who evilly entreat us are called by the same name as ourselves. Wherefore pray to the Lord yourself, and join all Christ's noble athletes with you in prayer for the Churches, to the end that, if any further time remains for this world, and all things are not being driven to destruction, God may be reconciled to his own Churches and restore them to their ancient peace.—St. Basil the Great, Letter 164
There is complete immunity in sinning; for when men have been placed in office by the favour of men, they are obliged to return the favour by continually showing indulgence to offenders. Just judgment is a thing of the past; and everyone walks according to his heart's desire. Vice knows no bounds; the people know no restraint. Men in authority are afraid to speak, for those who have reached power by human interest are the slaves of those to whom they owe their advancement.—St. Basil the Great, Letter 92
