The Council Fathers at Trent (1554-63) affirmed the ancient custom that the proper understanding of Scripture was that which was held by the Fathers of the Church to bring order out of the enveloping chaos. Opposition to the Church’s teaching is exemplified by William Webster (The Church of Rome at the Bar of History [Carlisle, PA: Banner of Truth Trust, 1995]) who misrepresents the Council Fathers by redefining and misapplying “unanimous consent”. First in redefining, he implies that unanimous consent means each Father must have held the same fully developed traditions and taught them clearly in the same terms as used later in the Church Councils. This is a false understanding of the phrase and even in American law unanimous consent “does not always mean that every one present voted for the proposition, but it may, and generally does, mean, when a [verbal] vote is taken, that no one voted in the negative” (Black’s Law Dictionary). Second he misapplies the term, not to the interpretation of Scripture, as the Council Fathers intended, but to tradition. His assertions are not true, but using a skewed definition and application of “unanimous consent”, he uses selective patristic passages as proof-texts for his analysis of the Fathers.
As an example, individual Fathers may explain “the Rock” in Matthew 16 as Jesus, Peter, Peter’s confession or Peter’s faith. Even the Catechism of the Catholic Church refers to the “Rock” of Matthew 16 as Peter in one place (CCC 552) and his faith (CCC 424) in another. Matthew 16 can be applied in many ways to refute false teachings and to instruct the faithful without emphasizing the literal, historical interpretation of Peter as the Rock upon which the Church has been built his Church. Webster and others emphasize various patristic applications of a biblical passage as “proof” of non-unanimous consent.
Discussing certain variations in the interpretations of the Fathers, Pope Leo XIII (The Study of Holy Scripture, from the encyclical Providentissimus Deus, Nov., 1893) writes, “Because the defense of Holy Scripture must be carried on vigorously, all the opinions which the individual Fathers or the recent interpreters have set forth in explaining it need not be maintained equally. For they, in interpreting passages where physical matters are concerned have made judgments according to the opinions of the age, and thus not always according to truth, so that they have made statements which today are not approved. Therefore, we must carefully discern what they hand down which really pertains to faith or is intimately connected with it, and what they hand down with unanimous consent; for ‘in those matters which are not under the obligation of faith, the saints were free to have different opinions, just as we are,’ according to the opinion of St. Thomas.”
