Quote from: Christianity Today articleBoer became president of Calvin at a time when the school had been under pressure to abide by the rules of the Christian Reformed Church in North America, in particular the church's teaching about sexuality. In 2022, the denomination ruled that congregations and church members must abide by church teaching on marriage and sex—which state that only heterosexual sex within marriage is allowed.
In the fall of 2022, Boer told Religion News Service that Calvin will continue to be hospitable to its LGBTQ students. "I don't want to be the president of an institution that isn't welcoming to everybody," Boer said.
That would be a different split between a board and a president than we are used to seeing. But also reflects a move away from the middle that is more common.
