Remember, then, that you received a spiritual seal, the spirit of wisdom and understanding, the spirit of knowledge and reverence, the spirit of holy fear. Keep safe what you received. God the Father sealed you, Christ the Lord strengthened you and sent the Spirit into your hearts as the pledge of what is to come.
AmbroseAs a servant desireth the approval of his master, and a son the approval of his father, so should we desire the approval of God and our own conscience.
AmbroseWe ask for what reason our Lord was unwilling to state the time of His coming (cf. Mk. 13:31-32). If we ask it, we shall not find it is owing to ignorance, but to wisdom. For it was not to our advantage to know; in order that we being ignorant of the actual moments of judgment to come, might ever be as it were on guard, and set on the watch-tower of virtue, and so avoid the habits of sin; lest the day of the Lord should come upon us in the midst of our wickedness.
Ambrose...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?
