Here is what they believe
Holy Spirit - The Holy Spirit is the Spirit of God, the life-giver. God lives by his own Spirit and had no other source.
Jesus Christ - Christ is the manifestation of God, the living Word, sent by the Father as a sacrifice
They see the Trinity as a "concept"
Who’s “they”? The Copts? Most Copts are not Coptic Catholics but Coptic Orthodox (but not in communion with Constantinople any more than they are with Rome), and I’d like to see your evidence that the Coptic *Catholics* (who are much less numerous than the Orthodox) believe anything like that.
