It is the Lord's commandment, but also the imperative of the present hour, to carry on dialogue with conviction at all levels of the Church's life. This must obviously take place with sincerity and realism, with patience and perseverance, in complete fidelity to the dictates of one's conscience in the awareness that it is the Lord who gives unity, that we do not create it, that it is he who gives it but that we must go to meet him.
