I think that questions related to defending the faith are important and I don't have the rep to created tags.
Would this be consider a feature request?
Yes you do!
Steve, rep restrictions are relaxed significantly in a private beta. You only need 1 rep to create a tag. Go ahead and create apologetics. Typically tags are not created instead they are just added to a question. If you for some reason cannot add a tag to a question just leave a comment or flag your question in order to have the tag added.
