Well, if and when The Temple is rebuilt....
Meanwhile, when were The Ten Commandments abrogated?
When was the last time you read Leviticus? There are many laws there about diet, rules of conduct, etc. that you don't follow. If you advocate following the law, then follow all of the law.
Well, if and when The Temple is rebuilt....
For the Church, Christ is the Temple. It's not a building. It is a Person.
Meanwhile, when were The Ten Commandments abrogated?
Again, it's not a matter of abrogation or abolition. The law is fullfilled in Christ and Christians are no longer subject to the Law. Following the law means following all of it and that is more that just the ten commandments. If you advocate following the law, then please do so, but don't just pick and choose what is convenient for you and ignore all the rest, and then claim that you follow the law.
