12 Recalling all these things, venerable brethren, with special interest during the solemn commemoration of the great Doctor, we shall find in them splendid examples for our admiration and imitation; nay, reflection on them will also furnish Us with strength and consolation amid the pressing cares of the government of the Church and of the salvation of souls, helping Us never to fail in our duty of co-operating with all our strength in order that all things may be restored in Christ, that "Christ may be formed" in all souls ( Galat. iv. 19), and especially in those which are the hope of the priesthood, of maintaining unswervingly the doctrine of the Church, of defending strenuously the liberty of the Spouse of Christ, the inviolability of her divine rights, and the plenitude of those safeguards which the protection of the Sacred Pontificate requires.
