Galatians 3:2 - Coke's Commentary on the Holy Bible

Received ye the Spirit, &c.— There is no doubt but that it was on their becoming Christians that they received the Spirit; and therefore that it could not be ascribed to the law, to which they were strangers till afterwards; but must be owing to that faith in which they were instructed by the gospel, on their embracing Christianity. Nor can it justly be objected that they still retained the Christianity by which the Spirit was received; for they were now perverted to a different system by their new teachers; and that which St. Paul had preached at first among them, was a Christianity of which Judaism made no part.
