[quote=ChiroCatholic]I’m sure this has been asked before, but perhaps someone can help me out.
What is a good, step-by-step way to answer a sincere Christian who believes that we should emphasize similaries, and downplay differences b/w denominations?
I converted to Catholicism, and have tried to evangelize to a non-Catholic Christian woman in her 50s. I think she could really use the fullness of truth (who couldn’t?) but I don’t know how to get past this initial obstacle. Any help? (Preferably in a tone where I wouldn’t feel like I was attacking her!)
I would start with the Catholic Church’s teaching that Scripture does contain the complete revelation of Jesus Christ. Certainly, it is the infallible word of God, but the first epistles were written years after Christ’s resurrection, and the Gospels followed decades later. What occurred in the intervening years was the Apostles and the presbyters establishing churches and teaching the doctrines of the faith as Christ had literally spoken directly to them. It is these teachings that the Catholic Church is based, which is why we have teachings about Mary, Purgatory, the Trinity, which are not explicitly covered in the Bible, but are true nevertheless, because Christ had revealed them to us.
Once you’ve established that there are doctrines of Christianity not established in the Bible, you can discuss the Catholic Church’s foundation on the Rock of Peter, as explained in Matthew.
And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it. I will give you the keys to the kingdom of heaven.Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven."
This passage shows how one can only view the Catholic Church as Christ’s church, which has the fullness of faith.
Peace and God bless!
