ISB ~ 1 Peter 1 v11

the Spirit of Christ:The Holy Spirit (1:12), who is sent into the world by the Father (Jn 14:26) and the Son (Jn 15:26). The activity of the Spirit is here linked with the inspiration of the Prophets, who spoke the word of God to Israel and foretold the suffering of the Messiah (e.g., Is 52:13— 53:12; Dan 9:26). Peter will return to this subject in his second letter, where he describes the Prophets being “moved” by the Spirit to speak messages that come “from God” (2 Pet 1:21).

• In the Nicene Creed, the Spirit is identified as the Divine Person “who has spoken through the prophets” (CCC 687, 702).
