Jewish rituals come from the Talmud not the Scriptures, you guys probably think the Sabbath is for the jews?
Isayah 56:1-7, "This is what Yahweh says: Keep the judgments, and do justly; for My salvation is near, soon, to come, and My righteousness to be revealed. Blessed is the man who does this, and the son of man who lays hold on it; who keeps the Sabbaths without polluting; defiling, them; and keeps his hand from doing dany evil. Do not let the son of the Gentile, who has joined himself to Yahweh, speak, saying; Yahweh has utterly separated me from His people. Nor let the eunuch say; Behold, I am a dry tree. For this is what Yahweh says: To the eunuchs who keep My Sabbaths, and choose those things which eplease Me, and hold fast to My covenant: I will give to them, in My House, even within My walls, a place; ministering position with power, and a Name equal to that of sons and of daughters; I will give them the Name of The Everlasting: YAHWEH; which will not be cut off. Also the sons of the Gentile who join themselves to Yahweh, to serve Him, and to love the Name of Yahweh, to be His servants--everyone who keeps the Sabbaths without polluting; de filing, them and who holds fast to My covenant--I will bring them to hMy holy mountain, and make them joyful in My House of prayer."
