I read this quote for Saint Athanasius of Alexandria in an Arabic book, but I am trying to locate the source (reference) of that quote (in which work for Athanasius), or something of the similar meaning by the saint.
"The Persons are not three gods, but rather they are one triune God with the consistency of His mind (the Father), His word (the Son), and His Spirit, who are the Father, the Son, and the Holy Spirit."
