That would be an ecumenical matter
This weekend I finished recording another document of the Church onto MP3. It is the decree on ecumenism from the Second Vatican Council, Unitatis Redintegratio.
In that vein, I’d also invite you to read the article Because our love has grown cold, written by my friend Nelson. I think his blog post points to the key thing which is needed in order for there to any meaningful ecumenical dialogue between Catholics and non-Catholics.
“My prayer is not for them alone. I pray also for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. I have given them the glory that you gave me, that they may be one as we are one — I in them and you in me—so that they may be brought to complete unity. Then the world will know that you sent me and have loved them even as you have loved me” – John 17:20-23
