here are my submissions. they work best in 1 color (and 1 color is cheap to reproduce) although they can also be made multiple colors. I didn't use the word 'church' but can easily incorporate it if you wish.
the concept is a tree (life) growing into and becoming intertwined with the gate to show relationship between church and congregation.
i am willing to make any changes or revisions you might have, just let me know. i will be on vaca from july 2 - 6 so i can make revisions when i return.
