" And when St. Cyril would give a rule to his crowd of Catechumens, "If ever thou art sojourning in any city," he says, "inquire not simply where the Lord's house is, (for the sects of the profane also make an attempt to call their own dens houses of the Lord,) nor merely where the Church is, but where is the Catholic Church. For this is the peculiar name of this Holy Body, the Mother of us all, which is the Spouse of our Lord Jesus Christ. "
