What does meet mean in liturgy where it says it is MEET and right so to do?

Answer 1

Proper.

In more detail:

"This exchange and affirmation between celebrant and people goes back to the 6th century liturgy of St John Chrysostom ('John of the Golden Mouth'), which is still used daily in the Orthodox Church. The Greek word translated as 'meet' is 'axion' from which we get 'axiom', meaning 'a proposition that commends itself to general acceptance, assented to as soon as stated'. The Shorter Oxford Dictionary defines 'meet' as: 'fitting, becoming, proper', with the Book of Common Prayer as reference."

Answer 2

In the context of liturgy, the term "meet" is used in its archaic sense to mean fitting, proper, or suitable. Therefore, when it is said that something is "meet and right so to do" in liturgical language, it is expressing that the action being performed is not only appropriate but also necessary and in accordance with the established traditions and practices of the church. This phrase emphasizes the significance and correctness of the action being undertaken within the religious ceremony.
