It is true that in sins of the sexual order, in view of their kind and their causes, it more easily happens that free consent is not fully given; this is a fact which calls for caution in all judgment as to the subject's responsibility. In this matter it is particularly opportune to recall the following words of Scripture: "Man looks at appearances but God looks at the heart."[²⁵] However, although prudence is recommended in judging the subjective seriousness of a particular sinful act, it in no way follows that one can hold the view that in the sexual field mortal sins are not committed.
