Read the proof, as given in the books quoted. Affected ignorance is a mortal sin. The authentic catechism states that to "impunge the known truth" is a mortal sin. Several heresies have been found not just in Trent, but also in Constance and Florence. To save one's soul, anyone must go back to the early Church dogmas and teachings of the true popes on Faith and Morals. Do your research before condemning those who love God and are preserving the true Catholic Deposit of the Faith. Another great apostacy heresy is that of the One Specie Heresy, promoted by Trent, Constance and Florence. This is the exact opposite teaching of the early popes and true Church Fathers in the first 1000 years of the Church. We are in the great apostacy the past 1000 years. Repent and go and sin nor more. In the early, true Catholic Church, the popes demanded at birth, Baptism, and the Two Species to infants, and asap, Confirmation. These 3 are absolutely needed for salvation. JohnTheBaptist.us
