“Therefore it is Our duty to help men and nations who are in distress, and to eliminate all present and threatening evils. For ‘Christ has given pastors and teachers for the perfecting of the saints, for the work of the ministry, for the building up of Christ's Body, until we all come together to the unity of faith and knowledge of God’s son.’ (Eph 4.12.) If ever anything deters, prevents, or delays any one of us from performing this task, what a disgraceful sin he will commit! Therefore, omit no watchfulness, diligence, care, and effort, in order to ‘guard the deposit’ of Christ's teaching whose destruction has been planned, as you know, by a great conspiracy.”  Pope Pius VII, Diu Satis, Par. 11
