Too many people think that keeping it earns salvation.
There is only ONE YHvH. He is the same forever. As there are many who reject the majority of the WORD of YHvH,
shalom b'SHEM Yah'shua HaMashiach

You don’t preach gospel then, whatever you do preach. You guys have gone wrong, period. God always was trinitarian from the very first “let Us” in Genesis. He waited until gospel times to show that character explicitly — possibly because it would have confused a world that He was seeking to rescue from a myriad of false (and disunited) gods if revealed too soon.
