A God-fearer is a term used to identify someone from a Gentile background who worships the Lord but has not been circumcised. This individual would have joined synagogue gatherings and forsaken the worship of idols.1 The fact that Cornelius and his family are said to be devout implies that his wife and children were also God-fearing.2
2 Cet homme était pieux et craignait Dieu, avec toute sa maison; il faisait beaucoup d'aumônes au peuple, et priait Dieu continuellement.
