We must be sensitive to weak believers who may think something we are doing in sinful (say, drinking a beer) and turn away from the church. It is best to suspend our conduct until we can assure him it is not an offense against God.
We believe that the community of God has the power to change such worship ceremonies in a way that may be most useful and edifying to the community of God.
Nevertheless, all frivolity and offense should be avoided in this matter. Special care should be taken to exercise patience toward the weak in faith (1 Cor. 8:9; Romans 14:13).
We believe that during a time of persecution, when a plain confession is required of us, we should not yield to the enemies in such matters of adiaphora. For the apostle has written in Galatians 5:1, "For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery." He also writes in 2 Corinthians 6:14, "Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?" Also note Galatians 2:5, "To them we did not yield in submission even for a moment, so that the truth of the gospel might be preserved for you." For in such a case it is no longer a question about adiaphora. But it concerns the truth of the Gospel, Christian liberty, and sanctioning open idolatry. It also concerns the prevention of offense to the weak in the faith. In such a case we have nothing to concede. We should confess and endure what God sends because of that confession, and whatever He allows the enemies of His Word to inflict on us. (pars. 63-65)
