"He cannot have God for his Father who does not have the Church for his Mother."
"There is need of constant prayer lest we defect from the heavenly kingdom, as have the Jews to whom it was first promised. This the Lord makes unmistakably clear by saying: "Many will come from the East and West and recline at the banquet table with Abraham and Isaac and Jacob in the kingdom of Heaven, whereas those born to the kingdom will be driven into the darkness outside, there to wail and gnash their teeth ..."
"Whosoever might be, and whatsoever he might be, he is no Christian who is not in Christ's Church!"
"Heretics or schismatics, being placed outside the Church and cut off from unity and charity, even though one should be slain for the name of Christ, he could not be crowned in death."
"Change nothing; be content with tradition."
