Saint Thomas Aquinas composed Sacris Solemnis at the command of Pope Urban IV for the new feast of Corpus Christi in 1264. The last two stanzas have become the hymn Panis Angelicus. I have always viewed this as the heart of the Summa set to music.
When he was canonized in 1323 some objections were raised because of a lack of miracles relating to the Angelic Doctor. Pope John xxii responded that every question Saint Thomas answered was a miracle.
Why we call God Father
1. He created us. We call God Father because He created us in a special way-namely, in His own image and likeness which He did not impress on other creatures here below: “He is thy Father Who made thee, and created thee.”
2. He governs us. We also call God Father because He governs us. For although He governs all things, yet He governs us as masters of ourselves whereas He governs other things as slaves of His will: “Thy providence, O Father, governs all things”. “Thou disposest of us with great favor”.
3. He adopted us. We call God Father because He has adopted us. For He endowed other creatures with trifling gifts, but to us He granted the inheritance, because (as the Apostle says) we are His sons “and if sons, heirs also”. “You have not received the spirit of bondage again in fear, but you have received the spirit of adoption of sons whereby we cry, Abba (‘Father’)”.
