Mystici Corporis Christi §35
Mystici Corporis Christi: On the Mystical Body of Christ
35 You are familiar, Venerable Brethren, with the admirable and luminous language used by the masters of Scholastic Theology and chiefly by the Angelic and Common Doctor, when treating this question; and you know that the reasons advanced by Aquinas are a faithful reflection of the mind and writings of the Holy Fathers, who moreover merely repeated and commented on the inspired word of Sacred Scripture.
