Ss Nereus & Achilleus and S Pancras. "all things have been handed over to me by my Father"

"no one knows the Father except the Son and anyone to whom the Son wishes to reveal Him"

-- Matthew 11:25-30

The duty of Christians to take part in the life of the Church impels them to act as witnesses of the Gospel and of the obligations that flow from it. This witness is a transmission of the faith in words and deeds. Witness is an act of justice that establishes the truth or makes it known.

All Christians by the example of their lives and the witness of their word, wherever they live, have an obligation to manifest the new man which they have put on in Baptism and to reveal the power of the Holy Spirit by whom they were strengthened at Confirmation.

-- CCC 2472
