I belong to no organization, although I do keep the Sabbaths and Feasts with others of like faith. I keep the commandments of Yahweh and faith in Yahshua:
[Rev 14:12 Here is the patience of the saints: here [are] they that keep the commandments of Yahweh, and the faith of Yahshua.]
Except for the animal sacrifices which have fallen into disuse because of the perfect sacrifice of the Messiah, keeping the Law has not changed. Faith in Yahshua is for our atonement, since he is our redeemer; and we are not yet "saved," but hope for it [Romans 8:24,25].
I know of no name for this faith, although "...my people which are called by my name" [2 Chr 7:14 & Dan 9:19] could bring my response that I am one of the "people of Yahweh."
