Hello Michael,
The Albigensians were a Heretical or False Christian faith with teachings that denied the Trinity and Divinity of Jesus Christ. When I speak of Martyrs, Im refering to those who died for the Religion or Chruch that Jesus Christ Founded and was carried on by the Apostles.. The definition of Martyr is pretty much summed up by dying for ones faith reguardless of what that faith is.. I imagine if a Satanist was killed for following the Church of Satan he would be called a Martyr.. Anyone in the Middle Ages who tried to start their own belief system reguarding Jesus and his Church had to be dealt with.. Unfortunatley, We cant do that anymore so now we thousands of incorrect versions of Christianity all leading people away from the Kingdom of Heaven.. Thanks for the Question,,, NEXT
