The activity program has various names in various jurisdictions. In GLofTX it is the Vanguard program or similar name. In Illinois it is the Grand Master's Award of Excellence program is it gets an acronym. I don't recall the California acronym. The idea is to give an activity goal to lodges and a few levels of annual award based on lodge size. Get enough points and you get photographed on the GL floor receiving your form. The program is supposed to set up a friendly rivalry of which local lodges can do how many of the points. Everything from ritual certifications through marching in a town parade. Some lodges view it as a competition so they frown on the program. Of course these are the lodges that are less active.
GL Masonry was founded on St John Day in London in 1717 is it is natural that one of the points be a lodge group attendance at a local church on one of the St John days as one of the points. It teaches Masonic history and gives us visibility in the community. Two services with one act.
When I was in the east the two times in Illinois the brother who was my SD then my JW is Catholic. We decided to standardize on going as a group to his church the St John day that's in the summer. Much of the decision had to do with maintaining a PR presence in that part of the suburbs as our representation near there declined once we sold our building and started meeting in the next suburb over.
