George Haydock's Catholic Commentary
Psalms 32:15
Every one, sigillatim. Hebrew yachad, means also "together;" whence the Origenists inferred (Haydock) that all souls were made at first with Adam. (St. Jerome) --- Thus they explained how they came to be all infected. (Berthier) --- But God rather creates them when he infuses them into the body. (Denis the Carthusian) (Haydock) --- St. Augustine could never decide this important question. This text only proves that God is equally Creator of all; (Ecclesiasticus xviii. 1.; Calmet) and He alone made the hearts and souls of all men, as Greek: katamonas implies, Psalm iv. 10., and Genebrard.
