Are Christians Permitted to Eat Unclean Animals?

[Rushing Jaws]

Morality is in regard to what we ought to do and we ought to obey God, so all of God's Laws are inherently moral. In 1 Peter 2:9-10, Gentiles are now part of God's chosen people, holy nation, a royal priesthood, and a treasure of God's own possession, so Gentiles also have the delight and the privilege of getting to obey the instructions that God gave for how to fulfill those roles.

A number of God's laws came with conditions under which they should be followed, so for example there is nothing wrong with not keeping the Sabbath holy when it is not the 7th day for the same reason that there is nothing wrong with not keeping God's laws in regard to temple practice when there is no temple in which to practice them.

The Torah says differently.

When the Israelites were in exile in Babylon, the condition for their return to the land was to first return to obedience to God's Law, which required them to have access to a temple that they didn't have access to while they were in exile, so we should be faithful to obey as much as we can obey.

Scripture makes no such limitation.

If we believe that God can be trusted to give laws for our own good in order to bless us, then we should have the attitude of looking for reasons for why we have the delight or getting to obey God's Law rather than the attitude of looking for every excuse under the sun to avoid following God's guidance. So there are both legitimate and illegitimate reasons for not obeying a particular law and there is a difference between someone who is not keeping the Sabbath holy because it is not the 7th day and someone is is not keeping the Sabbath holy because they are rebelling against what God has commanded.

The Torah commands keeping of the seventh day, and punishes disobedience to that commandment, which is one of the 10.
