Note 8 at Mt 19:11: Jesus did acknowledge that marriage is not for everyone. This would correspond to Paul's teaching in 1Co 7. However, both Paul and Jesus stressed that relatively few people were called to a life of celibacy (see note 9 at Mt 19:12). It has to be a calling. God is the one who looked at a sinless man and said that it was not good for him to be alone (Ge 2:18). So marriage is the rule, and living single for the sake of the Gospel is the exception. Paul, who advocated remaining single if a person was called to do so (1Co 7:24-28), said that it was a doctrine of devils to forbid marriage to anyone (1Ti 4:1-3).
