The Necessity of the Eucharist in John 6

Bishop Williamson opens this session by addressing the question of the necessity of receiving the Eucharist. He begins by reviewing the text of John 6:58-59, where Our Lord asserts that whoever eats His flesh and drinks His blood will live forever. The Bishop contextualizes this by comparing the necessity of the Eucharist with the necessity of baptism, noting that the Church has taught different requirements for these sacraments throughout history.

Following this, he walks through the specific theological implications of the text. He argues against the Utraquist view, which maintained that receiving under both species was strictly necessary for salvation, by citing the Church's historical practice. He contrasts the E-proposition (eating and drinking) with the A-proposition (eating), explaining that the predicate is universal in the former. He then digresses into a discussion regarding the state of souls who have fallen away from the faith, referencing the historical context of the Protestant Reformation and the Council of Trent. He also touches upon the concept of original sin and its transmission, and he evaluates the spiritual condition of those outside the Church, specifically referencing the status of Jews and Gentiles in the early Church.

He ends the lecture by emphasizing the importance of precise theological definitions. He reminds the students that while the Eucharist is a nourishment for the soul, it is not strictly necessary for salvation in the same way baptism is, especially for those who lack the opportunity to receive it. He concludes by cautioning the students against the errors of modernism and urging them to cling to the traditional teachings of the Church regarding the sacraments.
