John Broadus (1827–1895), second president of Southern Baptist Theological Seminary, Louisville, KY, unequivocally asserted his view of all infants dying in infancy in his classic commentary on Matthew’s gospel amidst his exposition of 19:14–“But Jesus said, ‘Let the children alone, and do not hinder them from coming to Me; for the kingdom of heaven belongs to such as these.’”
No question is here made that those dying in infancy are saved. They are saved through the atonement of Christ and the work of the Spirit, but this must hold true of all alike, without reference to any ceremony, and no matter whether their parents were believers, unbelievers, or heathen.
