'S Pius V's Breviary anticipated this Creed being said at the Divine Office on most of the Sundays after Pentecost. The Book of Common Prayer prescribed its use a dozen times a year.
They were right. It is as necessary as ever it was. Trinitarian errors still abound, and many of our present woes arise from faulty beliefs with regard to Catholic teaching about the Trinity and the Hypostatic Union.'
Nobody should say a word about the Trinity until they have read this creed.
