WNT(i)
2 One man's faith allows him to eat anything, while a man of weaker faith eats nothing but vegetables.
3 Let not him who eats certain food look down upon him who abstains from it, nor him who abstains from it find fault with him who eats it; for God has received both of them.
4 Who are you that you should find fault with the servant of another? Whether he stands or falls is a matter which concerns his own master. But stand he will; for the Master can give him power to stand.
5 One man esteems one day more highly than another; another esteems all days alike. Let every one be thoroughly convinced in his own mind.
