Do we still have to circumcise? Eat kosher food? Perform the various sacrificial offerings in the form of animals and grains? Support a levitical priesthood? Make annual pilgrimage to Jerusalem?

In Jesus' words:
"But it is easier for heaven and earth to pass away than for one dot of the Law to become void." (Luke 16:17 ESV)

"For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven." (Matthew 5:18-19 ESV)
