Benedict XVI welcomes Catholicos Aram I to the Vatican and recalls the shared history of faith and martyrdom between the Catholic and Armenian Churches, praying that ecumenical dialogue may advance full Christian unity. He then presents Paul's teaching on justification: human beings do not earn salvation by their own deeds but are made just through faith in Jesus Christ. Faith is a living communion rather than mere intellectual assent, and therefore expresses itself in charity and the fruits of the Spirit. Works cannot establish salvation independently, but true faith necessarily becomes active in love through the Spirit.
