Matthew 19:12
"For there are eunuchs, who were born so from their mother's womb: and there are eunuchs, who were made so by men: and there are eunuchs, who have made themselves eunuchs for the kingdom of heaven. He that can take, let him take it."
[This text is not to be taken in the literal sense; but means, that there are such, who have taken a firm and commendable resolution of leading a single and chaste life, in order to serve God in a more perfect state than those who marry: as St. Paul clearly shews. 1 Cor. 7. 37, 38]
1 cor 7 37-38
"For he that hath determined being steadfast in his heart, having no necessity, but having power of his own will; and hath judged this in his heart, to keep his virgin, doth well. Therefore, both he that giveth his virgin in marriage, doth well; and he that giveth her not, doth better."
