My mother is a Jehovah's Witness, which is a cult tied to the Masons. I have a friend who is a low-level Mason. There are people of good character I know who are Catholics. While I have a problem with secret societies and oaths that split loyalty, for me to disassociate myself with everyone who might be "tainted" in some way is self-sabotage.
The principle of staying clean and pure has to be squared with the consequences in our dirty yet real social environment. The reality of the terrain is that it has Satanic elements to navigate around. Staring at the heavens and wishing you were not bound to the land doesn't solve that.
We have ubiquitously infiltrated institutions, so guilt by association is going to get us nowhere. I have plenty of my own struggles with sin and mortal desire to confront before I go around passing judgment on others. Inevitable events will take care of the institutional corruption.
Jesus often hung with sinners and tax collectors ,prostitutes and others.. how else do we help others , especially those who know not what they do... we can’t help others understand, especially those who cannot see if we shun them from our light... my guess is that Martin has the ability and the backbone to see it through..to throw people away without trying is not very Christ like... I for one applaud Martin and his ethics. I trust his control of the situations he encounters.
