...Now since you are celebrating the holy Pascha, you should know, brethren, what the Pascha is. Pascha means the crossing-over, and so the Festival is called by this name. For it was on this day that the Children of Israel crossed over out of Egypt, and the Son of God crossed over from this world to His Father. What gain is it to celebrate unless you imitate Him Whom you worship; that is, unless you cross over from Egypt, that is, from the darkness of evildoing to the light of virtue, from the love of this world to the love of your heavenly home?

Ambrose... the Apostle Peter declared that the Church was built by the Holy Spirit. For you read that he said: 'God, Who knows the hearts of men, bore witness, giving them the Holy Spirit, even as was given to us; and He made no distinction between us and them, purifying their hearts by faith' (Acts 15:8-9). In which is to be considered, that as Christ is the Cornerstone, Who joined together both peoples into one, so, too, the Holy Spirit made no distinction between the hearts of each people, but united them.
