[All] of us, believers in Christ, have been called to proclaim the mighty works of God. Beyond the differences which still separate us, we recognise with joy that at the origin of our Christian life there is always a call from God himself. We can make progress on the path to full visible communion between us Christians not only when we come closer to each other, but above all as we convert ourselves to the Lord, who through his grace, chooses and calls us to be his disciples. And converting ourselves means letting the Lord live and work in us. For this reason, when Christians of different Churches listen to the Word of God together and seek to put it into practice, they make important steps towards unity.
