St. Vincent of Lerins and Heresy Again

Dr. Bryan Cross has a great piece at Called To Communion on Saint Vincent of Lerins method of determining heresy. I have quoted from Saint Vincent before as he makes it historically clear that the principle of "sola scriptura" was not the accepted standard for determining doctrine in the 5th century. As you will see from Bryan's article and my previous posts, Saint Lerins shows us that the Church uses both Sacred Tradition together with Holy Scripture to determine what teachings are orthodox and devoid of error, not just man-made personal interpretation of Sacred Scripture. It has always been enlightening to me to realize that the Church defended the doctrine of the Trinity in (325 AD) even before the New Testament was canonized (382 AD). This proved that scripture alone could not settle the Aryan heresy threatening to split the Church, because they weren't even decided at that point which circulating epistles and books were Scripture!

Keep in mind: "Almost every heresy that has disturbed the unity of the Church has been advocated by men who appealed to Scripture in confirmation of the doctrines they taught."
