Charles Ellicott Commentary Acts 10:2

"a devout man, and one that feared God with all his house, who gave much alms to the people, and prayed to God always." — Acts 10:2 (ASV)

A devout man, and one that feared God with all his house.—The word for “devout” is not the same as that used in Acts 2:5, Acts 8:2, and Luke 2:25, and appears to be used by St. Luke, as again in Acts 10:7, for the special type of devotion that belonged to Gentile converts to Judaism. The phrase “those that feared God” is employed distinctly for this class in Acts 10:22, Acts 10:35, and again in Acts 13:16, Acts 13:26. There is a special significance in the addition “with all his house.” The centurion was not satisfied with having found a higher truth for himself, but sought to impart it to the soldiers and slaves, possibly to those nearer and dearer to him, who came under his influence .

Which gave much alms to the people—that is, to the Jews of Caesarea as distinct from the Gentiles (Compare to Acts 26:17, Acts 26:23, and Acts 28:17).

And prayed to God alway.—As the vision that follows may rightly be regarded as an answer to the prayers thus offered, it is natural to infer that Cornelius was seeking guidance regarding the new faith which Philip had brought to Caesarea, and of which he could scarcely fail to have heard. Was it really a new revelation from God to man? Could he be admitted to the fellowship of the society which confessed Jesus as the Christ without accepting the yoke of circumcision and the ceremonial law, from which, as a “proselyte of the gate,” he had until then kept back?
