That's an important distinction to draw, between the synagogue and the Church. We need to take that distinction further, and discern the difference between the earthly system of worship associated with an earthly tabernacle system, and the heavenly worship of the saints of the assembly, as is fitting for a heavenly system. I don't believe it should be a matter of prohibiting things - we shouldn't have to go about making rules to keep elements of Jewish worship out of the Church. We should be so caught up with the heavenly things we have to do with, that nothing earthly has any sway with us! "Remember not the former things", says God, "neither consider the ancient things: behold, I do a new thing; now it shall spring forth: shall ye not know it?" (Isaiah 43:18-19). Shall we not know it? Shall we be too much occupied with types and shadows, "the former things", to behold what God is doing NOW? "I do a new thing" - doesn't that speak of such vital freshness? It isn't that God changes, or that He gives up any of His plans and counsels, no. Yet He does a new thing, He brings in something fresh, so as to make us forget the old.
