Some are incapable of marriage because they were born so; some, because they were made so by others; some, because they have renounced marriage for the sake of the kingdom of heaven. Whoever can accept this ought to accept it.
(Matt 19:12)Indeed, I wish everyone to be as I am, but each has a particular gift from God, one of one kind and one of another. Now to the unmarried and to widows, I say: it is a good thing for them to remain as they are, as I do, but if they cannot exercise self-control they should marry, for it is better to marry than to be on fire.
(1 Cor 7:7-9)
“Whoever can accept this ought to accept it.”
He does not say MUST accept it.
