I have just decided to publish the Sarum Ordo at the beginning of each month. Over the course of this year, I have found errors and omissions and have pencilled in corrections for next year’s complete ordo. This has not a patch on the famous Ordo from the Saint Lawrence Press for the Roman liturgy according to early twentieth century liturgical norms. This work is not a copy of the St Lawrence Press Ordo because it is for the Use of Sarum, not the Roman Rite.
Here is my humble contribution, which includes some feasts from the Roman rite, missing in the Sarum Use. Those feasts are in italics. Naturally, I am following the Gregorian Calendar. If you find errors or omissions according to Sarum norms, please note this in a comment.

The Blue Flower 
Quite a few of the Greek Fathers missing from the Sarum kalendar.
This is something I have noticed. St Gregory of Nazianus is also not present in the 1474 Missale Princeps. On 9th May, one finds Beati presbyteri martyris. It would be worthwhile finding out when the Greek and Cappadocian Fathers began to find their way into the Roman Rite.
What is interesting is how the 1568/70 Roman Calendar gives broad parity to Eastern and Western Doctors. I do wonder whether someone on the Commission was thinking of ‘sweetening’ the East in the face of the then Turkish threat with a view to a possible reconciliation?
It’s possible. Nevertheless, the Roman Office remained largely ”Roman,” with lessons mostly from Sts Augustine and Ambrose.
When does corpus christi enter the calendar?
7th June. I am publishing this ordo month by month.
