The first major division of the Millerite groups who had not completely given up their belief in Christ’s Second Advent were those who accepted a shut-door theology. This belief was popularized by Joseph Turner and was based on that key Millerite passage: Matthew 25:1–13—the Parable of the Ten Virgins. The shut door mentioned in verses 11–12 was interpreted as the "close of probation". As Knight explains, "After the door was shut, there would be no additional salvation. The wise virgins (true believers) would be in the kingdom, while the foolish virgins and all others would be on the outside."
