Freemasonry has been a good association for my family. My father was one, my daughter was in Job's Daughters (which is very remarkable, because she isn't much of joiner in anything!)
There is too much in Masonry that is incompatible with Scripture. And I have met too many Masons who value their Masonic lodge more than they do their church. Christ died for the church, according to Scripture, not these kinds of organizations. I have known many good men who were Masons, however, and I know they are involved in many good benevolent endeavors.
Masonry as a fraternal organization of men to have fellowship and do good works seems benign enough. But many have made it their religion.
But, I think it was very useful during times of social upheaval and persecution to have an organization that one could meet with in secret with a trusted group of men and discuss ideas that were considered dangerous or treasonous with the governmental powers that be.
