Augustine of Hippo

Pascha (passover) is not, as some think, a Greek noun, but a Hebrew: and yet there occurs in this noun a very suitable kind of accordance in the two languages. For inasmuch as the Greek word paschein means to suffer, therefore pascha has been supposed to mean suffering, as if the noun derived its name from His passion: but in its own language, that is, in Hebrew, pascha means passover; because the pascha was then celebrated for the first time by God's people, when, in their flight from Egypt, they passed over the Red Sea... And a most salutary transit we make when we pass over from the devil to Christ, and from this unstable world to His well-established kingdom. And therefore surely do we pass over to the ever-abiding God, that we may not pass away with this passing world. The apostle, in extolling God for such grace bestowed upon us, says: "Who hath delivered us from the power of darkness, and hath translated us into the kingdom of the Son of His love."
