Chapter 18
Each minister may assemble with his brothers every year wherever he may please on the Feast of St. Michael the Archangel, to treat of those things which belong to God. And let all the ministers who are in parts beyond the sea and beyond the mountains come once in three years, and the other ministers once every year to the chapter on Whit Sunday [Pentecost], at the Church of St. Mary of the Portiuncula, unless it be otherwise ordered by the minister and servant of the whole brotherhood.
