First Reading 1 Peter 1:10-16
10About this salvation, the prophets inquired and diligently searched, those who prophesied about the future grace in you,
11inquiring as to what type of condition was signified to them by the Spirit of Christ, when foretelling those sufferings that are in Christ, as well as the subsequent glories.
12To them, it was revealed that they were ministering, not for themselves, but for you those things which have now been announced to you through those who have preached the Gospel to you, through the Holy Spirit, who was sent down from heaven to the One upon whom the Angels desire to gaze.
13For this reason, gird the waist of your mind, be sober, and hope perfectly in the grace that is offered to you in the revelation of Jesus Christ.
14Be like sons of obedience, not conforming to the desires of your former ignorance,
15but in accord with him who has called you: the Holy One. And in every behavior, you yourself must be holy,
16for it is written: “You shall be holy, for I am Holy.”
