And the human authors who wrote knew nothing of any sexual orientation, only understood as deliberate perversion.
Understanding Scripture with the Church
66 "The Christian economy, therefore, since it is the new and definitive Covenant, will never pass away; and no new public revelation is to be expected before the glorious manifestation of our Lord Jesus Christ."28 Yet even if Revelation is already complete, it has not been made completely explicit; it remains for Christian faith gradually to grasp its full significance over the course of the centuries.
109 In Sacred Scripture, God speaks to man in a human way. To interpret Scripture correctly, the reader must be attentive to what the human authors truly wanted to affirm, and to what God wanted to reveal to us by their words.75
110 In order to discover the sacred authors' intention, the reader must take into account the conditions of their time and culture, the literary genres in use at that time, and the modes of feeling, speaking and narrating then current. "For the fact is that truth is differently presented and expressed in the various types of historical writing, in prophetical and poetical texts, and in other forms of literary expression."76
- "through the contemplation and study of believers who ponder these things in their hearts";57 it is in particular "theological research [which] deepens knowledge of revealed truth".58 CCC
