According to what is written in the Old Testament: "You shall hold a holy meeting on the first day, and you shall hold a holy meeting on the seventh day. You shall not work on those days" Ex. 12,16. If we look at what is written, the question that should not arise is whether it is Saturday or Sunday that prayer can be done, for both are holy days of assembly.
