WEST WARWICK — For the past seven years, Catholic Underground PVD at St. Patrick Church on Smith Hill has drawn a devoted following of young adults eager to encounter Christ through Eucharistic adoration, live music, and creative expression. Now, the Diocese of Providence’s Secretariat for Evangelization and Pastoral Planning hopes to carry that same spirit beyond the city with Ocean State Underground, a traveling version of the popular event designed to reach Catholics across Rhode Island.
