1039 Freising Pontifical and the Filioque

 In the 1039 Pontifical of Freising, from Germany, in the section for Baptism, which follows the Old Roman Ordo of apportioning out the Catechumenate, especially in the last week of Lent, we have noticeable items like the tradition [giving] of the Our Father and Symbol.

In the section for the giving of the Symbol of Faith [i.e. the Credo in Unum Deum], it gives, like in the Gelasian Sacramentary, the Symbol to be recited in Greek and Latin.  

In the Symbol in Greek (transliterated into Latin letters), we have chant notation above the words; the text is given absent the infamous "Filioque" addition.

However, only a page or two later, when the Symbol is recited in Latin, the notorious addition of "Filioque" is lamentably found in the Latin text.

This, as we have noted in previous posts, is different than in the Pontifical of Poitiers, which gives the Greek and Latin text of the Symbol absent the "Filioque", as well as in the 1025 Subiaco Missal, which similarly gives the Greek and Latin text of the Symbol unaltered as well. 

I speculate that that a certain high degree of importance was attached to the Greek text of the Symbol in Latin books, as you will often find chant notation attached to the Greek Symbol over against the Latin in the Catechumenate; this gives a certain degree of added solemnity, and, even in the 11th century as the "Filioque" addition found its place more and more in different books in the Latin West, more often than not the Greek text was always preserved in Latin books free from corruption.
