Isidore of Seville and the Filioque

The introduction and proliferation of the double procession of the Holy Spirit formulae in Hispania is a rich topic. There are aspects of it that have been somewhat marginalized, however. Surprisingly, one of those is the evidence from Isidore of Seville, the most celebrated churchman of the seventh century. He had a role in spreading the double procession/ Filioque of the Holy Spirit through some of his works and a council. This study for the first time brings them all together to assess the place of Isidore in making normative the Filioque in the broader context of Visigothic Hispania. This study intends to contribute to the approaching celebration of the 1700 anniversary of the Creed of Nicaea, 325-2025.
