Union Chapel’s Sunday services in Oak Bluffs have spread messages of hope and unity all summer long, and organizers are anticipating a spirited final two sermons.

Rev. Dr. Aliya Browne, president of the chapel’s board of trustees, said this year’s series has taken on a new energy as worshipers are suffering from job layoffs, are worried about the loss of medical insurance and the direction of the current presidential administration.

“I think that in general, people are looking to improve their faith in something because of the times that we’re living in,” Dr. Browne said. “Many people are turning towards their God to try and double down on that.”

Union Chapel’s robust programming brings new and returning speakers from different denominations and backgrounds to the pulpit. This Sunday, Dana Allen Walsh from South Church in Andover will deliver a sermon on holy curiosity during uncertain times. She co-hosts a podcast titled A Life Worth Working using the tagline “the reverend that wears Prada.”

“She’s a very dynamic preacher with excellent messages,” Dr. Browne said. “She’s jovial, she’s got a lot of energy [and] she brings a good knowledge and a good punch.”

Dr. Browne will deliver the final sermon of the summer on August 31, which will focus on holistic health. She specializes in integrative cardiology at Martha’s Vineyard Hospital.

“It is important for us to not only physically get ourselves in good health, but to always spiritually be thinking about how we can improve our spiritual life,” she said.

The summer programming kicked-off on Juneteenth with a sermon by Rev. Dr. Michael Eric Dyson, a professor at Vanderbilt University who has authored over 25 books, the most recent being Represent: The Unfinished Fight for the Vote which explores the country’s ongoing struggle for voting rights.

Rev. Otis Moss III, the senior pastor of Trinity United Church of Christ in Chicago, returned on the first Sunday in August as he has done for many years.

Dr. Browne said Reverend Moss has drawn the largest crowd thus far.

“It’s always amazing how he preaches and... brings us to really think about our part in creating the community that we want to see,” she said.

Union Chapel participated once again in the Festival of Worship in Word and Song at the Tabernacle, in conjunction with the Martha’s Vineyard Camp Meeting Association and the First Congregational Church of West Tisbury, and headlined by Rev. Sen. Raphael Warnock.

Rep. Ayanna Pressley, Bishop Vashti Murphy McKenzie, the president and general secretary of the National Council of Churches of Christ, and Bishop Donald Hillard Jr., a senior pastor of Cathedral International, also delivered sermons this summer.

“We’ve had some great preaching, great singing and great spiritual life at the church,” Dr. Browne said.
