John Chrysostom
"Therefore," he proclaims, "invoke a blessing. In what manner? 'The Lord bless thee, and keep thee.' Observe how, throughout Scripture, God reveals the mystery of the Trinity; for His sake, these blessings are expressed in threes. 'The Lord bless thee, and keep thee; may the Lord make His face shine upon thee and be gracious unto thee' (Num. 6:24-26). See how the sacred Trinity is exalted. What grace exists that does not come from the Holy Spirit? What gift is not bestowed by Him? What goodness can be achieved without His presence? What precious gift could possibly reach humanity apart from the Holy Spirit? Delve into the Scriptures and note how, when describing anything accomplished through divine power, all credit is given to the action of the Spirit."
