Christian literally means follower of Christ.

Christ is greek for messiah.

The messiah is a huge part of Judiasm.

Basically, Christianity is just Judaism in a way from the Christian perspective.

Jesus was a Jew.
His apostles were all Jews.

Why Christians can eat pork and not observe the sabbath has to do with parts of the old law being types and shadows of the messiah and his kingdom.

For example, the passover lamb represents Jesus dying on the cross.
No need to observe the passover feast after Jesus died.

But if you don't believe Jesus is the messiah, you would think to still observe passover due to the type and shadow not being a thing for you.

Basically, from this view, many things in the old law where do them because I said so.
Many of those no longer apply because it has be revealed God's plan of salvation and those were part of a tapestry of prophecy and metaphor.
