Bp. Butler’s notes address aspects of the U.S. Lutheran-Roman Catholic agreed statement of 1978. The agreed statement is available along with study papers in: Lutheran-Roman Catholic Dialogue in the U.S.A., Teaching Authority & Infallibility in the Church, Lutherans and Catholics in Dialogue VI, ed. by Paul C. Empie, T. Austin Murphy, and Joseph A. Burgess (Minneapolis: Augsburg Publishing House, 1978).
The Lutheran-Roman Catholic agreed statement was also published in Theological Studies 40, no. 1 (March 1979): 113-166. It is this edition that Bp. Butler’s notes reference.
