St. Ambrose examines and refutes the heretical argument that because God is said to be glorified in the Spirit, and not with the Spirit, the Holy Spirit is therefore inferior to the Father. He shows that the particle in can be also used of the Son and even of the Father, and that on the other hand with may be said of creatures without any infringement on the prerogatives of the Godhead; and that in reality these prepositions simply imply the connection of the Three Divine Persons.
