But if they are required then in such a case where reasonable required obedience can be met, then we should follow "lest we should offend them:"
And when they were come to Capernaum, they that received tribute money came to Peter, and said, Doth not your master pay tribute? He saith, Yes. And when he was come into the house, Jesus prevented him, saying, What thinkest thou, Simon? of whom do the kings of the earth take custom or tribute? of their own children, or of strangers? Peter saith unto him, Of strangers. Jesus saith unto him, Then are the children free. Notwithstanding, lest we should offend them, go thou to the sea, and cast an hook, and take up the fish that first cometh up; and when thou hast opened his mouth, thou shalt find a piece of money: that take, and give unto them for me and thee. (Matthew 17:24-27)
You are apparently casting your pearls before swine. According to some on this thread wearing a mask to church equates to worshipping satan.
