Matthew Henry, Commentary on the Whole Bible… (1700s)
“ If, while we seek justification by Christ alone, and teach others to do so, we ourselves are found giving countenance or indulgence to sin, or rather are accounted sinners of the Gentiles, and such as it is not fit to have communion with, unless we also observe the law of Moses, is Christ the minister of sin? Will it not follow that he is so, if he engage us to receive a doctrine that gives liberty to sin, or by which we are so far from being justified that we remain impure sinners, and unfit to be conversed with? ”
