The Solemnity of the Most Holy Trinity. Father Dave says that Trinity Sunday, many pastors use metaphors to try to explain the Trinity (everything from a shamrock to a fidget spinner!) Father Dave emphasizes that the Trinity is a mystery that we can never fully understand. Instead we should embrace the mystery of it, and form a community that comes together because of it. Preached at St. Paul the Apostle Church, New York City on 06-11-17.
