Is virginity more meritorious than marriage, according to St. Paul in 1 Corinthians 7?

Is, according to St. Paul in 1 Corinthians 7 , the state of virginity more meritorious than that of marriage? Catholics think it is, and some (all?) Protestants think it is not. Why? For example, the Council of Trent says: > Canon X.—If any one saith, that the marriage state is to be placed above the state of virginity, or of celibacy, and that it is not better and more blessed to remain in virginity, or in celibacy, than to be united in matrimony: let him be anathema.
