But as he which hath called you; God the Father, to whom, as the First Cause, our calling is frequently ascribed, Romans 9:11,24 1 Corinthians 7:15 Galatians 1:6,15. It may be rendered: According to the Holy One that hath called you, i.e. according to his example; you are children, and should therefore imitate your Father, Ephesians 5:1. Called you; viz. effectually, to the knowledge and faith of Christ. Is holy; so God is often styled by Isaiah and other penmen of the Scripture, as the fountain and exemplar of holiness. So be ye holy in all manner of conversation; either, through the whole course, and in the several parts, of your conversation; or, in all manner of conversation, as we read it, i.e. with whomsoever ye converse, believers or infidels, friends or enemies, relations or strangers; and in whatsoever condition ye are in, peace or trouble, prosperity or adversity.
