For, also, insofar as, according to the divine command, he loves his neighbor as himself and for him, he knows that this brethren in faith and in the Christian name are imprisoned by the faithless Saracens in a cruel prison and endure the harsh yoke of slavery, he does not expend the efficacious work for their liberation, that the Lord spoke of in the Gospel. "Do to others whatever you wish them to do to you". Or perhaps you do not know that many thousands of Christians are held in prison and slavery by them and they suffer countless torments?"
