The following is the note I left in the Order's comment form.
To the officers of the Order of Malta in the United States:
Terry McAuffile's addition to your fine order will only result in scandal for you and for the Universal Church the order serves. A man who can proclaim his Catholic identity while at the same time supporting in the public square positions that are diametrically opposed to the doctrine of the Church he professes his loyalty to does not belong in the Order of Malta.
I ask you to reconsider offering him membership. I will pray for your members and your great works around the world.
