And so much for a rational discussion ... Have Nice Day.
Rational or rationalistic?
Very well, by your choice it is the end. But I will have you note that you didn’t want to answer specifically on two matters, first, in regard to the theology of the creeds, which - here is my admission - is the theology of the Holy Scriptures, and second, your reluctance (near refusal) to deal with the fact that the Bible calls Mary the mother of Jesus. Why, I asked myself, why? What is the issue here? You gave me only your speculations, quickly resorting to the terminology of genetics and avoiding the plain language of the Bible.
Your problem, my friend, is a Christological one. You have some issue in regard to the incarnation of Him who is “God of God, Light of Light, Very God of Very God, begotten not made, being of one substance with the Father, by whom all things are made.” In this realm “rational(istic) discussion” is the opposite of faith. Faith takes God at His word. Faith does not put together a rational construct, cherry picking what it wants from the Bible, and in which it then invests believe. That is rationalism.
