“We must, then, maintain that Christ has two energies in virtue of His double nature. For things that have diverse natures, have also different energies, and things that have diverse energies, have also different natures.” – St. John Damascene
“O faithful, let us acclaim the lover of the Trinity, great Maximos who taught the God-inspired Faith, that Christ is to be glorified in two natures, wills and energies: and let us cry to him: Rejoice, O herald of the Faith.” – Kontakion to St. Maximus the Confessor
“He being one Son, dual in Nature, not dual in Person. Wherefore, do we confess, preaching the truth that Christ our God is perfect God and perfect Man.” – (Troparion of the Resurrection on the Feast of the Holy Forefathers).
Comment: It has been said many times that if one attended all the unabbreviated services of the Church – the full cycle of Holy Week, marriages, funerals, makings of catechumens, etc., this would teach one the entire doctrine of the Church, for nothing is rightly believed that is not prayed, and nothing is rightly prayed that cannot be believed. -DD
