This is the spiritual reality regardless if you are Protestant or Roman Catholic. A person must be born again to receive the Word of God as the Word of God. No church authority can open the heart of an unregenerate to receive the Word of God as the Word of God with a transforming effect. The Scripture and God’s truth is concealed until the Spirit of God reveals it to the elect of God. Here are two essential passages to make my point. Notice that Paul thanks God that some are able to receive the Word of God as the Word God. This has nothing to do with the Roman Catholic Church. All the glory goes to God alone. Water baptism does not cause a person to be born again. Therefore, many who have partook in water baptism cannot understand the things of God, because they are still dead in their sins and treaspasses, seperated from God. If water baptism is the instrument that God grants the new birth, why do some Roman Catholics have no desire and affection for God?
1 Thessalonians 2:13
And we also thank God constantly for this, that when you received the word of God, which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers.
Luke 10:21
In that same hour he rejoiced in the Holy Spirit and said, “I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and revealed them to little children; yes, Father, for such was your gracious will.
