It is error to believe that Every man is free to embrace and profess that religion which, guided by the light of reason, he shall consider true.

The Roman Pontiffs have always...held that all those rites should be preserved which deviate neither from accuracy in matters of faith, nor from what is fitting.

The most Blessed Virgin Mary, in the first instant of her conception, by a singular grace and privilege granted by almighty God, in view of the merits of Jesus Christ, the savior of the human race, was preserved free from all stain of original sin.

Neither the true faith nor eternal salvation is to be found outside the Holy Catholic Church.

If anyone says that it is possible that at some time, given the advancement of knowledge, a sense may be assigned to the dogmas propounded by the Church which is different from that which the Church has understood and understands: let him be anathema.

If a future Pope teaches anything contrary to the Catholic Faith, do not follow him.

Give me an army saying the Rosary and I will conquer the world.
