K2 brought up an interesting point about Torah observance by Christians, and asked why it wasn't seen and encouraged in the early Church. So I did just a littel digging, because I remembered from prior reading that Torah observance was widespread in early Christianty, especially the Eastern Churches.
Below is a reference to the "circumcised bishops" of Jerusalem. From the time of James until 130 AD, the bishops of Jerusalem were all circumcised, Torah observant Jews. So for one hundred years after the death of Christ the bishops in charge of the birthplace of Christianity were all Torah followers.

I've also waxed on about the Quartodecimian controversy on several occasions. Basically this dispute was over the celebration of Passover and the resurrection of Jesus. The Western Churches wanted a Sunday observance, and the Eastern Churches wanted to use the 14th day of Nisan (the first Jewish month). K2 says this was only a disagreement on the celebration of the actual day. I disagree, and I see this as a clear disagreement between Torah observant Christians and those who were not. Moving on...
John Chrysostom was bishop of Constantinople in the late 4th century. He specifically wrote a tract titled "Against Jews" as referenced.

In Homily 1 part 5, you can see that he mentions Christians in relation to the Jewish Festivals and High Holy Days. He says many go to observe and some participate in the Festivals with the Jews. He is appalled and speaks out vehemently against this. But it is clear evidence that even in the late 300's AD Christians were still keeping Jewish Festivals as part of Torah.
Further reading in Socrates Church History volume #6 states that Chrysostom forcibly took churches from "quartodecimian bishops," and sometimes used physical violence to accomplish this. Due to this and other actions, he was eventually deposed from his position. It seems weird to me that we still had so many Eastern bishops referred to "quartodecimian" even into the late 4th century. After all, wasn't the matter of Passover settled hundreds of years earlier? I think Chrysostom's actions and writings are further evidence of my view that "quartodecimian" was a catch-all term used to describe Torah observant Eastern believers.
As a tangent, I wanted to discuss the Nestorians. Nestorius was excommunicated for teaching that Jesus' divine and human nature were distinct and no seemlessly blended. That's not why I'm bringing him up. Nestorius spent time in both Antioch and Constantinople, and he was known to be a devout monk. After the schism of his followers from the mainline Church, it was noted that they all observed the sabbath and abstained from pork. Again, this is around 400 AD. Nestorius and his followers always maintained that their views were perfectly orthodox and never considered themselves part of a different Church. They were cut off; they didn't choose to leave. However, they were not excommunicated over sabbath or dietary practices, and there is no history anywhere that says they just decided to start doing these things after the schism. Coupled with the other practices mentioned earlier, it makes sense to me that they were already avoiding pork, keeping Sabbath (and perhaps other types of Torah observance as well) well before the schism and just continued worshipping as they always had.

(Section 5, banned practices)
Finally there are many references to sabbath keeping in early church, especially the East. In fact, as late as the late sixth century we still had popes issuing edicts trying to force Christians to work on Sabbath and rest on Sunday. As people don't make these announcements with no reason, it is fair to assume a significant number of Christians were still following Sabbath worship.
