Other thoughts and commentary on the 2nd Reading:
**20b But if you are patient when you suffer for doing what is good, this is a grace before God: **To put this verse in context, we must read the preceding two and one-half verses: “18 Slaves, be subject to your masters with all reverence, not only to those who are good and equitable but also to those who are perverse. 19 For whenever anyone bears the pain of unjust suffering because of consciousness of God, that is a grace. 20a But what credit is there if you are patient when beaten for doing wrong?”
**21 For to this you have been called, because Christ also suffered for you, leaving you an example that you should follow in his footsteps: **Not following in His footsteps to slavery, but to the patient suffering of unjust wrongs, for Christ provided us all a perfect example of this.
“Be sure to note carefully the extent to which Peter beholds glory even in the state of slavery, by saying that those who do well and are blameless but who are beaten by cruel and dishonest masters, are following in the footsteps of Christ, who suffered unjustly on our behalf. That is something to rejoice about!” [Saint Bede the Venerable (ca. A.D. 416), *On 1 Peter
]

22 “He committed no sin, and no deceit was found in his mouth.”: **This begins the hymn referred to in the introduction (read Isaiah 53:4-12). The innocent servant of Yahweh, as described by the Isaiah, five hundred years earlier, had to bear injuries, insults and bodily sufferings. What a perfect model he was for a suffering slave of that day. “He was (to be) led like a lamb to the slaughter and like a sheep that before its shearers is dumb, he opened not his mouth” (Is. 53: 9). St. Peter sees Christ fulfilling to the letter the role of the suffering servant as Isaiah had described the future Messiah.

23 When he was insulted, he returned no insult; when he suffered, he did not threaten; instead, he handed himself over to the one who judges justly:
Christ had full confidence in his Father’s decisions. He left himself entirely in his hands.

24 He himself bore our sins in his body upon the cross: Literally, “… to the wood”. “Wood” or “tree” is a very early term for the cross. Christ carried the sins of men up to the cross in His body, undergoing the “curse” for them. The “curse” is the result of breaking the covenant with God. Adam and Eve had broken their covenant with God; the Israelites, at Mount Sinai, had broken their covenant with God and had brought the “curse” upon themselves and their descendants. It was on the cross that Jesus fulfilled the role of the suffering servant (see Galatians 3:13; Deuteronomy 21:23). 2nd Corinthians 5:21 says “For our sake he made him to be sin who did not know sin, so that we might become the righteousness of God in him.” Christ is acknowledged as sinless (verse 22 of our reading today; Hebrews 4:15) yet through God’s choice He came to stand in that relation to God which is normally the result of sin—He became part of a sinful humanity so that His sacrifice would open heaven and allow our sins to be forgiven (see Romans 6:10-12).
*“Christ was nailed to the cross, paying the penalty not for His own sins but paying the debt of our nature. For our nature was in debt after transgressing the laws of its maker. And since it was in debt and unable to pay, the Creator Himself in His wisdom devised a way of paying the debt. By taking a human body as capital, He invested it wisely and justly in paying the debt and thereby freeing human nature.” *[Theodoret of Cyr (ca. A.D. 430), *On Divine Providence, 10,26]
so that, free from sin, we might live for righteousness. By his wounds you have been healed: The death of Christ on the cross obtains pardon for all the sins of mankind provided man asks for that pardon. All Christians in their baptism have symbolically died with Christ, died to sin, and have begun to live the new life of sons of God, living in righteousness.
25 For you had gone astray like sheep: Before their conversion they were like lost sheep (another reference to Is. 53: 6), not knowing whence they had come nor whither they were going.
but you have now returned to the shepherd and guardian of your souls: Now that they have become Christians their lives, in this world and the next, are under the leadership and protection of the Good Shepherd, a term Christ had used for himself (Jn.10: 11, see 10: 1-17).
The familiar shepherd and flock figures express the care, vigilance, and love of God for His people in the Old Testament [Psalm 23 (our Responsorial Psalm); Isaiah 40:11; Jeremiah 23:4-5; Ezekiel 34:11-16] and of Jesus for all humanity in the New Testament [Matthew 18:10-14; Luke 15:4-7; John 10:1-16 (our gospel reading); Hebrews 13:20].
