Happy Feast of St Thomas Becket

Today is the Feast of St Thomas of Canterbury, that great English Saint of the Middle Ages. It is also the only day that I am aware of when King David is commemorated liturgically.

The Martyrologium Romanum, according to the online version of the 1911 Breviary, began its entry for today thus:

Cantuáriæ, in Anglia, natális sancti Thomæ, Epíscopi et Mártyris, qui, ob defensiónem justítiæ et ecclesiásticæ immunitátis, in Basílica sua, ab impiórum hóminum factióne percússus gládio, Martyr migrávit ad Christum.

Hierosólymis [At Jerusalem] sancti David, Regis et Prophétæ.

This morning was not particularly pleasant. Mais que faut-il faire?
