First and foremost, if you are a Christian you should be a 'Yorkie'; thus, Knight Templar.
Second, yes I am a retired Marine and enjoy the military aspects of the YR, just as I enjoy being a member of my VFW ritual team.
Third, military and religion are needed together, look at what is happening around you. (Also active political efforts for the American way.)
Fourth, time is a short commodity these days and the respective YR body should make every effort to work around your schedule, with you doing everything to make it happen.
Fifth, to keep members coming deemphasize the need to immediately get a uniform.
