Wtenbogaert strove for religious tolerance. He was greatly admired and therefore often portrayed. In 1619, the year in which the Remonstrants were expelled, the printmaker Delff published a portrait of Wtenbogaert, based on a painting from 1612. Thirteen years later, by which time the clergyman was 75 years old and living in Holland again, Delff made another portrait of him, now after a painting by Van Miereveld.
