The 7th day Sabbath (Subota) is still kept, it simply pails in comparison to the Lord’s day. The fact is the Jews who did not convert after hearing the word reject God. They rewrote scripture to deny the messiah and are not Christians, nor freinds of anything like the truth Christians acknowledge, if you follow them check out revelations to see where it leads.
Dang, you’re on a roll. First you claim Christians never attempted to observe Sabbath before 200 years ago and, secondly, you say the Torah denies Jesus ever came even though it was written over a thousand years earlier. You sure you didn’t eat some matzeh that contained the blood of little gentile children during the Easter season? lol.
