Innocent III, 1198-1216

Profession of Faith Prescribed for Durand of Osca and His Waldensian Companions¹

[From the letter "Eius exemplo" to the Archbishop of Terraco, Dec. 18, 1208]

420. By the heart we believe, by faith we understand, by the mouth we confess, and by simple words we affirm that the Father and the Son and the Holy Spirit are three Persons, one God, and entire Trinity, co-essential and consubstantial and co-eternal and omnipotent, and each single Person in the Trinity complete God as is contained in "Credo in Deum," [see n. 2] in "Credo in unum Deum" [see n. 86], and in "Quicumque vult" [see n. 39].

423. By the heart we believe and by the mouth we confess the one Church,
