"When, by God's help and the prayers of the Apostles, you come into the country of the Greeks, if bishops choose to meet you receive them with all due respect. If they propose a night-lodging for you do not refuse, that laymen may not suppose you will hold no union with them. But if they invite you to eat with them, courteously excuse yourselves, saying, Pray that we may first be joined at the Mystical Table, and then this will be more agreeable to us. Do not, however receive provision or things of that kind, except carriage, if need be, but excuse yourselves, saying that you have everything, and that you hope that they will give you their hearts, in which abide all gifts, charity and unity, which make up the joy of religion. "So, when you reach Constantinople, go wherever the emperor appoints; and before you see him, let no one approach you, save such as are sent by him. But when you have seen the emperor, if any orthodox persons of our own communion, or with a zeal for unity, desire to see you, admit them with all caution. Perhaps you may learn from them the state of things. "When you have an audience of the emperor, present your letters with these words: 'Your Father greets you, daily intreating God, and commending your kingdom to the intercession of the holy Apostles Peter and Paul, that God who has given you such a desire that you should send a mission in the cause of the Church and consult his holiness, may bring your wish to full completion'. "Should the emperor wish, before he receives your papers, to learn the scope of your mission, use these words: 'Be pleased to receive our papers'. If he answer, 'What do they contain?' reply, 'They contain greeting to your piety, and thanks to God for learning your anxiety for the Church's unity. Read and you will see this.' And enter absolutely into nothing before the letters have been received and read. When they have been received and read, add: 'He has also written to your servant Vitalian, who wrote that he had received permission from your piety to send a deputation of his own to the holy Pope, your Father. But as it was just to direct these first to your majesty, he has done so; that by your command and order, if God please, we may bear to him the letters which we have brought.'
