Jerome — as excerpted in the Catena Aurea on Matthew 22:23-33

“There were two sects among the Jews, the Pharisees and the Sadducees; the Pharisees pretended to the righteousness of traditions and observances, whence they were called by the people ‘separate.’ The Sadducees (the word is interpreted ‘righteous’) also passed themselves for what they were not; and whereas the first believed the resurrection of body and soul, and confessed both Angel and spirit, these, according to the Acts of the Apostles, denied them all, as it is here also said, Who say that there is no resurrection. (Acts 23:8.)”
