Gieschen believes that ontological concerns (questions concerning the being of Christ) have "inhibited" Angelomorphic studies undertaken in the past. He proposes that we should now ask another question in place of the ontological ones, namely, "Where and how did early Christians use the variegated angelomorphic traditions from the OT and other sources to express their Christology?" Consult Angelomorphic Christology, 349.
His new formulation of the Angelomorphic question is designed to show that Angelomorphic traditions significantly influenced early Christology qua high Christology. Gieschen further maintains that traditions portraying Christ as the visible manifestation of God's Son (the malak YHWH) paved the way for later Christological affirmations such as "Jesus is Lord" (1 Cor. 12:3) or YHWH. See ibid. 350.
While he tries to downplay questions concerning the being of Christ in his study, it is evident that Gieschen espouses a high Christology, linking the Son in his role as an angel with a/the visible manifestation of YHWH.
