It seems they can’t make up their minds of whether they are Nestorians, Eutychians, or Apollinarians.
What is clear is that Evangelical Christology is fundamentally heretical.
Do you agree with the Apollinarians?
Apollinarianism is a fourth-century Christological heresy. Named after Apollinarius of Laodoecia, its main author, Apollinarianism teaches that Jesus Christ had a human body and a human soul but no human rational mind (nous), because the Divine Logos had taken its place. Apollinarianism was condemned at the Second Ecumenical Council together with Macedonianism and other Christological and Trinitarian heresies. Adherents of Nestorianism sometimes accused Orthodox and monophysite theologians of Apollinarianism.
I think it's because protestants never had to go through these heresies. They never had to develop their thoughts on it and see all the possible variations of belief about the Incarnation and who Jesus is, and don't realize they cannot all be true and have the same orthodox faith.
It's an argument from ignorance in many cases. IMHO anyway.
