Translation of "responsio" into English

Haec responsio videri potest difficilis, sed est simul firma et vera: in ea solutio certa ac definita continetur.

This reply may seem difficult, but at the same time it is firm and it is true; it bears within itself the definitive solution.

Nihilo minus Christi responsio in semet ipsa valet tum in viros tum in mulieres.

Nevertheless, Christ's answer, in itself, has a value both for men and for women.
