Here are some of my concepts. I've gone for something that's fairly clean and simple, yet striking. Creating an icon that works well within the logo or as a stand alone element, one that can be used for things like favicons or watermarks.
The logos are 100% vector so will scale well to any size, and works well in full colour, B&W and on coloured backgrounds if needed.
It would be my pleasure to work up any variations so please do say. I look forward to your comments or thoughts.
Could you also terminate the arms of the cross 2/3rds of the way back so we can see block beyond the arms. Remove the lines that create the C's. Make the cross brownish tan. Make the grey colors more of lighter tan. Make the word Cornerstone red to bring more focus to it. Make Church the brownish tan.
