But not as Christ commanded. He said do this in remembrance of me--not symbolically once or twice a year. "Keep the Sabbath holy," and how better than to A) do what Christ commanded, and "do in remembrance" of Him, and B) remember that most holy sacrifice He made.
I am always amazed at these threads that turn into Catholic vs Protestant debates. Arguing about Holy matters is legalistic and unseemly. Such discourse ignores the supreme fact that God is love, not doctrine. One cannot argue one's way into Grace.
