Receive him that is weak in the faith, but not for passing judgment.

Ambrosiaster
AD 400
As I mentioned in my prologue to the epistle, those who led the Romans to faith had mixed it up with the law because they were Jews, which is why some of them thought that they should not eat meat. But others, who followed Christ apart from the law, thought otherwise, that it was permissible to eat meat, and for this reason there were disputes among them. The apostle tried to solve these disputes by arguing that the person who abstained from eating gained no advantage in the sight of God, nor did the one who ate lose anything thereby. He says that the person who is afraid to eat because the Jews had forbidden it is weak. He wants this person to be left to his own judgment, so as not to be hurt and depart from that love which is a mother of souls. Commentary on Paul’s Epistles.
