Angainor:
Accept him whose faith is weak, without passing judgment on disputable matters. One man’s faith allows him to eat everything, but another man, whose faith is weak, eats only vegetables. The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him. Who are you to judge someone else’s servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand.Romans 14:1-4 (NIV)
The context of this is that Jewish converts were a little hesitant to eat meats that had formerly been “unclean” to them. For centuries their relatives were forbidden from eating these meats. All of their lives, they had been told that these meats were unclean and should be avoided.
Suddenly, these meats were no longer unclean, and they were allowed to eat them. It is very understandable that they would be a little hesitant to eat those foods. Their faith (the Christian faith) told them these meats were now clean, but some were still hesitant to eat them.
That is what Paul was addressing. What he was saying was that those who had a strong faith and had no problem eating the formerly unclean meat, should not judge those who were hesitant to eat them. After all, no one is required to eat those meats to be a Christian. It was an indifferent matter. And when something is indifferent, people should not argue about it and isolate others.
But there is a big difference between an indifferent thing, such as eating certain foods, and rejecting doctrines, which is what Luther did. The Bible makes a clear distinction. The quote you provided shows that when we are dealing with such secondary and indifferent matters as what food we eat, we should not judge another.
However, when we are dealing with doctrine the Bible is clear that if someone teaches a false doctrine they are to be avoided. And the only way to know if their doctrine is false is to “judge”.
“A man that is a heretic, after the first and second admonition, avoid: knowing that he that is such a one is subverted and sinnieth, being condemned by his own judgment” (Titus 3:10-11)
Luther was one such heretic. He rejected what was taught by Christ and His apostles, and invented a false form of Chritianity to justify his guilty conscience. “I burn " said Luther " with a thousand flames in my unsubdued flesh: I feel myself carried on with a rage towards women that approached madness. I, who ought to be fervent in spirit, am only fervent in impurity” (Table Talk).
Luther, in order to justify his conscience, revolted and did not continue in the doctrine of Christ. “Whosoever revolteth, and continueth not in the doctrine of Christ, hath not God… If any man come to you, and bring not this doctrine, receive him not into the house nor say to him, God speed you. For he that saith unto him, God speed you, communicateth with his wicked works” (2 John 1:9-11).
