40 It is true that the Fathers and Scholastics had a great deal to say about symbolism in the Eucharist, especially with regard to the unity of the Church. The Council of Trent, in re-stating their doctrine, taught that our Saviour bequeathed the Eucharist to His Church "as a symbol . . . of the unity and charity with which He wished all Christians to be joined among themselves," "and hence as a symbol of that one Body of which He is the Head."
