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.
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.
AmbroseIf someone offends you, don't tell anyone about it except your elder, and you will be peaceful. Bow to everyone, paying no attention whether they respond to your bow or not. You must humble yourself before everyone and consider yourself the worst of all. If we have not committed the sins that others have, perhaps this is because we did not have the opportunity - the situation and circumstances were different. In each person there is something good and something bad; we usually see only the vices in people and we see nothing that is good.
