The Fourth Lateran Council (A.D. 1215) was convoked by Pope Innocent III “to eradicate vices and to plant virtues, to correct faults and to reform morals, to remove heresies and to strengthen faith, to settle discords and to establish peace, to get rid of oppression and to foster liberty, to induce princes and Christian people to come to the aid and succour of the Holy Land”. The Constitutions present a dogmatic formulation on Transubstantiation. Image above links to Tanner translation of the Council decrees. ISBN recommendation: 0-87840-490-2
