Excerpt from an Easter Sermon by Gregory Nazianzen (bishop of the Eastern church in the late 300s):
“Let us become like Christ, since Christ became like us. Let us become God’s for His sake, since He for ours became Man. He assumed the worse that He might give us the better; He became poor that we through His poverty might be rich; He took upon Him the form of a servant that we might receive back our liberty; He came down that we might be exalted; He was tempted that we might conquer; He was dishonoured that He might glorify us; He died that He might save us; He ascended that He might draw to Himself us, who were lying low in the Fall of sin. Let us give all, offer all, to Him Who gave Himself a Ransom and a Reconciliation for us. But one can give nothing like oneself, understanding the Mystery, and becoming for His sake all that He became for ours” (Oration I.5).
