Renewal of Faith
In Deuteronomy 4:2 we read "In your observance of the commandments of the LORD, your God, which I enjoin upon you, you shall not add to what I command you nor subtract from it." One of the objections raised by people who do not understand the Catholic Church is that it adds to the teachings of the Lord.
This is a misunderstanding of the teachings of the Catholic Church. The Catholic Church does not offer its teachings to add (or subtract) to what the Lord asks of us. Rather, the Church offers its writings to help us discover what the Lord's teachings mean in our world today.

Perhaps one of the areas that most touches upon our Christian beliefs in the scientific field is medical research. The Church offers its teachings on such questions as "is stem-cell research morally acceptable."

"In your observance of the commandments of the LORD, your God, which I enjoin upon you, you shall not add to what I command you nor subtract from it." Deuteronomy 4:2
