On the following day Paul went in with us to James, and all the elders were present. When he had greeted them, he told in detail those things which God had done among the Gentiles through his ministry. And when they heard it, they glorified the Lord. And they said to him, "You see, brother, how many myriads of Jews there are who have believed, and they are all zealous for the law; but they have been informed about you that you teach all the Jews who are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children nor to walk according to the customs. Acts 21:18-21

While some cultural traditions are innocuous, and therefore fine for Christians to celebrate, some are clearly in opposition to Christ and must not be celebrated by Christians. But there is a third category. What about traditions that may be okay, but become so important in people’s minds that they take on a spiritual/religious significance? And worse, what if believers revere these traditions so highly that they impose them on others?

First, anything that gains this much of a priority in our lives, though not sinful in and of itself, is dangerous! To quote the Apostle John, “Keep yourselves from idols!” (1 John 5:21) In addition…

I am guessing that the answer is clearly in the question. We must always be on guard about allowing anything to become so important in our lives. When we do, those things have become idols in our lives. Idolatry of any kind is among the chief of sins! If and when we impose our idolatry on others, it becomes doubly bad.

So be careful about otherwise innocent matters than can become idols, and for sure, do not impose such things on others!
