Fr. Gilsdorf begins to close by looking at Vatican II. In this penultimate lecture, Fr. Gilsdorf analyzes the ‘extraordinary Synod’ which had to be called to settle the misunderstandings that were becoming widespread concerning Vatican II. Fr. Richard Gilsdorf discusses the breach between Holland and Poland, where the problem lies with the interpretation of Vatican II. Father Gilsdorf, therefore, searches scripture for a better understanding of the important word “communion,” and how we can work to be in holy communion with the Holy Trinity.
