Naming Protestant churches after saints?

You will drive around your average town in the United States, Canada or any part of the Anglophone world and see many church buildings - St. Mark, St. John, St. Anne, etc. There's a caveat - they're mostly Protestant. 

It is an enigma as to why Protestants use names of canonized saints because of the nature of Protestantism - a heresy, and the nature of canonized sainthood - those who lived the Catholic faith and are deservedly in heaven, promulgated as such by a valid pope - invalidate the other. 

There is no one alive today who would be canonized by a Pope if they promoted such fallacies like sola scriptura, faith by grace or the denial of critical Catholic dogmas like the Primacy of Peter or the Marian dogmas. To their credit, they believe in the Sacred Trinity - that is where the Catholic faith ends in the Protestant religion.

So, is it really correct for Protestants to use the name of holy, canonized saints in the names of their church buildings? In truth, no. I can't control, nor can anyone but Our Lord, control what Protestants do, but naming castles of heresy after canonized saints is an act of vituperation against the Church. 

Saints are in heaven because they promoted the Catholic faith or in the case of martyrs, died for It. 

No one is a saint for heresy and schism or a martyr for schism. If there were people who died for the newly-formed Anglican sect when it was beginning to form from distorted Catholic rites and sacraments, they died for nothing. If there were Catholics protecting the Catholic Church from the infiltration of Protestant thinking, they were martyrs.

God bless you.
