Today is the 505th anniversary of the beginning of the Protestant Deformation, so I think this is very apropos. Remember, all validly baptised people are members of Christ's Church until they embrace heresy after the age of reason.
-Saint Teresa of Avila (1582): “It was that vision (of Hell) which filled me with very great distress. I had the greatest sorrow for the so many lost souls that condemned themselves to Hell, especially those Lutherans. - for they were once members of the Church by Baptism - and also gave me the most vehement desires for the salvation of souls [...] I saw souls falling into hell like snowflakes.”
