Entry #10: I really like this. I think I'd want a monstrance in there somewhere -- I'm less interested in the flame and people graphics. (That holds true of #11 and #12 as well -- I'd rather see a chalice or something like that instead of the people graphics.)
Now that I'm seeing a lot of burgundy in these logos, I'm thinking I don't love it. I like the gold of the background -- and the tan on #10 -- but the burgundy is to me less attractive than the blue of #11, I think.
I love the script font idea in #8 and #9 for the slogan, but I am not crazy about that particular font. I'll have to look at my fonts and see if there is one that might work better. Since the school is all about rigor, I'd want something more formal and less breezy.
I love the idea of #8, esp since I can separate the word from the image. Inside the yellow circle, it would work better to have either an IHS or a cross or a chi rho:
I have uploaded a couple of new options using a monstrance and different layouts. Let me know how you feel about those. In any case, further suggestions are appreciated.
