E04220: A confession of faith, which any Jew converting to Christianity within the Visigothic kingdom was obliged to subscribe to, includes the promise to observe Sundays and the feasts of the martyrs. Latin law of King Ervig issued in 680 in Spain and included in the codification known as the Lex Visigothorum.

Lex Visigothorum, Book XII, Chapter 3, § 14

Professio Iudeorum, quomodo unusquisque eorum ad fidem veniens indiculum professionis sue conscribere debeat.

'Profession of the Jews - how any of them coming to the faith should subscribe to a statement of their profession'

There follows the profession whereby a person rejects the Jewish religion and customs, confesses the Christian faith in the form of the Nicene-Constantinopolitan creed, promises never to return to the Jewish religion, to avoid the company of Jews, to live always in a Christian way, to share meals only with Christians, and to go frequently to church.

Sed et in festivitatibus dominicis sive etiam in martyrum festis, quas Christiane religionis pietas observandas decrevit, ita promitto eas ipsas festivitates devote suscipere et cum summo amore amplectere et in his ipsis diebus semper christianis honestissimis interesse, sicut honesta et pia christianorum consuetudo id facere vel suscipere consuevit.

'And I also promise to celebrate devoutly all Sundays and the feasts of the martyrs which the piety of Christian religion decreed to be observed, and I will accept them with the greatest love and on those days I will spend my time with good Christians as it is done and observed according to the good and pious custom of the Christians.'
