False teachers & unity

To the Church -
Beloved and enlightened in your love for our God Jesus Christ, joined together by the Will of Him who wills into being all things:

Flee for you lives from men who deny God, who have no faith, who deny Christ's genuine sufferings (theological liberals); they are poisonous growths with a deadly fruit, and one taste of it is speedily fatal. They are none of the Father's planting; if they were, they could at once be known for true branches of the Cross, and there would be no corruption in their fruit. It is by the Cross that though His Passion He calls you, you who are parts of His own body, to Himself. A Head cannot come into being alone, without limbs; for the promise that we have from God is the promise of unity, which is the essence of Himself.
