His persistence would seem to be based on wanting to convert you not in wanting to know the truth.
The Catholic belief in faith and good works is supported in Scripture.
Here are a few quotes
James 2:14-24 "What does it profit, my brethren, if a man says he has faith but has not works? Can his faith save him? If a brother or sister is ill-clad and in lack of daily food, and of you says to them, âGod in peace, be warmed and filled,â without giving them the things needed for the body, what does it profit? So faith by itself, if it has no works, is dead. But some one will say, âYou have faith and I have works.â Show me your faith apart from your works, and I by my works will show you my faith. You believe that God is one; you do well. Even the demons believe- and shudder. Do you want to be shown, you foolish fellow, that faith apart from works is barren? Was not Abraham our father justified by works, when he offered his son Isaac upon the altar? You see that faith was active along with his works, and faith was completed by works, and the scripture was fulfilled which says, âAbraham believed God, and it was reckoned to him as righteousnessâ; and he was called the friend of God. You see that a man is justified by works and not by faith alone.
** Luke 6:46-49 **"Why do you call me Lord, Lord, and not do what I say?
Everyone who comes to me an listens to my words and
acts on themâI will show you what he is like. He si like a man who when he builds his house dug deeply, and laid the foundations on rock; when the river was in flood it bore down on that house but could not shake it, it was so well built. But the one who listens but does nothing is like the man who built his house on soil, with no foundations; as soon as the river bore down on it, it collapsed; and what a ruin that house became ]

Philippians 2:12-13 **âTherefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling; for God is at work in you, both to will and to work for his good pleasure.â
Galatians 6:7-9 âDo not be deceived; God is not mocked, for whatever a man sows, that he will also reap. For he who sows to his own flesh will from the flesh reap corruption; but he who sows to the Spirit will from the Spirit reap eternal life. And let us not grow weary in well-doing, for in due season we shall reap, if we do not lose heart.â
