I didn't have time to respond to this yesterday as I saw it at the end of my workday and I only really had time to move it over to meta where it belonged.
Usually I try to explain myself a bit better when I do something like a delete an answer, but this didn't seem to be your first misadventure with posting a comment as an answer so I was a bit harsher than I normally am, because continuing in behavior you've been warned against is not a good idea and leads to harsher responses.
However, now that you've got the permission to comment, much of what I'd otherwise say is irrelevant. What I will say is that reputation based privileges is a hallmark of the SE system, as Caleb has said, the reason for that is that the main thrust of the sites is asking and answering, we want people to start doing those things first before they can do anything else. Once they've earned a little bit of reputation via those things, they get more privileges, like unfettered editing, commenting and close/reopen/delete/undelete votes.
Now a bit about your answer and experience.
You are not being specifically targeted. We get dozens of flags from normal users every day asking us to take a closer look at questions, comments and answers with a limited set of tools do deal with them if they require our involvement (namely deleting answers and closing questions).
Moderation here is stricter than other places you may have been on the network. This in part comes with controversial subject matter, but it's also because of a number of other things. We're a fairly high traffic site at this point, and that means a lot of cruft comes in and is dealt with swiftly. It also means that more things are lost in the shuffle, if I don't delete a post that is out of place and clear the flag, I'm not likely to see that post again and then it's back until someone else maybe notices it in 6 months or a year. But google still sees it and it's still there as a broken window for someone else.
We have a highly active flagging community here. I didn't just stumble across your post, another user flagged it for moderator attention. In general we don't go looking for posts to delete, usually if we delete something it's because someone brought it to our attention and we decided that it was not a good fit for the site.
The last point, if you believe that an answer is an answer, don't start it with "If only I could comment, I'd do that." If you don't follow that up with a strong answer, it's going to get flagged and a moderator is going to delete that.
On a last note. We try really hard not to censor anyone who can back up where their beliefs come from and show that they are reflective of even the smallest group of Christians. We've had some real crackpots (no offense intended to anyone) come through here and participate constructively, we've had some people with very biblically solid beliefs struggle to participate positively here.
