Except for your "Siloam" I thought your original showed more promise.
I know this looks 70's, but to me, it looks like "International Typographic Style"
or "Swiss".

Starting around the 40's to the 60's. Near the end of that style, the
magazine that championed the 70's version of Swiss was Avant Garde... the
original typeface came from the design of the magazine which was used and
abused way too much.
There are a few books, most rare. Books by Yasaburo Kuwayama catalogued many
of the logo's of that era.

I think the king of modern swiss is:

My opinion is: The logo should be able to stand alone (no elongated drop
shadows or enclosure) and then be able to be used in various formats.
This may look to "plain wrap (

with the type some more.
Look at the images below, the logo has that shadow, and can
stand alone. I'm not a huge fan of the actual logo, but like how
they integrated it into the marketing and wall graphics.
The color and the colors of the drop shadows are odd.
Why stop at this one idea, do you have anymore ideas?
The last ones are awkward... I don't know how long you have been a designer
and if you went to school, but the last ones are not showing the experience you
seem to have.
I would polish up your original idea, then I would research and try
a few ideas.. not just the one
