Quotes from Pope Pius IX

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 state (the U.S. Constitution) has not the right to leave every man free to profess and embrace whatever religion he may desire.

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

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.

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