From the Roman Catholic perspective, always Saint Thomas More. From the Anglican perspective, always Sir Thomas More.

Being a secular humanist, I always preferred Saint Sir Thomas More. This Catholic don't seem to have no problem with it. Besides, why would a Catholic deprecate a title bestowed by a secular goverment at that time allied with Rome? But it was a joke, son. I say, a joke. Also, the Anglicans don't seem to have a problem with the papist title of Fidei Defensor given to Henry VIII for a book ghosted by Sir Thomas More ...

Ceci n'est pas un seing.
