Why not sign up for an account? I thought to myself. Oh well.http://www.newadvent.org/cathen/05022a.htm"... The term diptych is often restricted to a highly ornamented type of notebooks...In the fourth and fifth centuries a distinction arose between profane and ecclesiastical (liturgical) diptychs...Whatever their immediate purpose the liturgical diptychs admitted only the names of persons in communion with the Church; the names of heretics and of excommunicated members were never inserted. Exclusion from these lists was a grave ecclesiastical penalty; the highest dignity, episcopal or imperial, would not avail to save the offender from its infliction...The order of which traces are now seen in the Roman Canon of the Mass was the fixed usage of the Roman Church as early as the fifth century."

[This was before Nestorius’ condemnation by the Third Ecuмenical Council.] When the most pious Bishop Eulalius learned of this, he was anxious about the outcome of the affair. And seeing that it had been noised abroad, Nestorius also ordered him to reprimand Hypatius. For Nestorius was still powerful in the city. Bishop Eulalius spoke thus to Hypatius: ‘Why have you erased his name without understanding what the consequences would be?’ Saint Hypatius replied: ‘From the time that I learned that he said unrighteous things about the Lord, I have no longer been in communion with him and I do not commemorate his name; for he is not a bishop.’ Then the bishop, in anger, said: ‘Be off with you! Make amends for what you have done,
for I shall take measures against you.’ Saint Hypatius replied: ‘Do as you wish. As for me, I have decided to suffer anything, and it is with this in mind that I have done this.’

"...In former times, at this place in the Canon, the name of the king was mentioned after that of the bishop: et Rege nostro N. …but since St. Pius V issued his missal for general use, this has been omitted."
