We who are strong ought to bear with the failings of the weak and not to please ourselves. Each of us should please our neighbors for their good,to build them up. For even Christ did not please himself but, as it is written: “The insults of those who insult you have fallen on me.” For everything that was written in the past was written to teach us, so that through the endurance taught in the Scriptures and the encouragement they provide we might have hope.
May the God who gives endurance and encouragement give you the same attitude of mind toward each other that Christ Jesus had, so that with one mind and one voice you may glorify the God and Father of our Lord Jesus Christ.
Accept one another, then, just as Christ accepted you, in order to bring praise to God.
Weak and strong have to do with the changes that were taking place with the coming of the new covenant in which many rules, even the schema of the old covenant, was being put aside since the fulfillment of it in Christ and through his death, had already come. It was not an easy time, a time of change. It was not like Christians at that time had to put all the old practices aside. But they had to accept the new reality that other Christians were not going to practice them, and would still be completely accepted by God, so that they too would need to accept them. They were the majority at first, but in a matter of a relatively short time would become the minority as more and more Gentiles would come to the faith.
We can apply this passage in a looser sense with strong and weak perhaps signifying scruples and religious practices. What might be out of bounds for some, might not be any problem for others. Of course I’m not talking about out and out sin, but rather things that might lead some, the “weak” into sin. What might not be a problem for me might be an occasion of stumbling for them, so that I won’t be acting in love if I flaunt my freedom in their presence.
Also I need to be careful not to judge others on things which in themselves are not sin, covered by God’s grace. I might possibly be termed as “weak” in those situations. God looks at the heart. Some practice might be better than others, and maybe it doesn’t matter. But oftentimes what we know is best for us, or what we’re accustomed to, we impose on others, and judge them according to those standards. Which might in fact not be helpful to them, even if they might possibly learn something from our own practice.
We must accept one another fully, even as Christ has fully accepted us, that we together might bring glory to God. A big part of that is simply learning to get along well with our differences, some of that contrast perhaps being uncomfortable to us like the sound of chalk on a blackboard. For this to happen, we need to pray, and be open to the work of the Spirit in drawing us together in harmony, so that in that, we might bring praise together to God. Getting along with each other is a high priority to God. And the essence of what it means to be “in Christ.” Of course as those who are seeking to live in the grace and truth of our Lord. In and through Jesus.
