141 Him that is weak in the faith receive ye, but not  to doubtful disputations.
141 Accept the one whose faith is weak, without quarreling over disputable matters.
141 As for the one who is weak in faith, welcome him, but not to quarrel over opinions.
141 Welcome with open arms fellow believers who don't see things the way you do. And don't jump all over them every time they do or say something you don't agree with - even when it seems that they are strong on opinions but weak in the faith department. Remember, they have their own history to deal with. Treat them gently.
141 Receive one who is weak in the faith, but not to disputes over doubtful things.
141 Accept other believers who are weak in faith, and don't argue with them about what they think is right or wrong.
Matthew Henry's Commentary on Romans 14:1
Commentary on Romans 14:1-6
(Read Romans 14:1-6)
Differences of opinion prevailed even among the immediate followers of Christ and their disciples. Nor did St. Paul attempt to end them. Compelled assent to any doctrine, or conformity to outward observances without being convinced, would be hypocritical and of no avail. Attempts for producing absolute oneness of mind among Christians would be useless. Let not Christian fellowship be disturbed with strifes of words. It will be good for us to ask ourselves, when tempted to disdain and blame our brethren; Has not God owned them? and if he has, dare I disown them? Let not the Christian who uses his liberty, despise his weak brother as ignorant and superstitious. Let not the scrupulous believer find fault with his brother, for God accepted him, without regarding the distinctions of meats. We usurp the place of God, when we take upon us thus to judge the thoughts and intentions of others, which are out of our view. The case as to the observance of days was much the same. Those who knew that all these things were done away by Christ's coming, took no notice of the festivals of the Jews. But it is not enough that our consciences consent to what we do; it is necessary that it be certified from the word of God. Take heed of acting against a doubting conscience. We are all apt to make our own views the standard of truth, to deem things certain which to others appear doubtful. Thus Christians often despise or condemn each other, about doubtful matters of no moment. A thankful regard to God, the Author and Giver of all our mercies, sanctifies and sweetens them.
