"It is clear that the person who is selective in his acceptance and rejection of diverse items in the deposit of revelation is not accepting what he does accept on authority of God's revealing it but on the basis of his own private judgement. This supermarket approach of selecting some doctrines and rejecting others makes it obvious that God's word is not the reason for this person's religious commitment."
-Thomas Dubay in Faith and Certitude.
Let us also remember the words of St. Peter:
"First of all you must understand this, that no prophecy of scripture is a matter of one's own interpretation, because no prophecy ever came by the impulse of man, but men moved by the Holy Spirit spoke from God." -2 Peter 1:20-21
