EFS proponent: We believe that the Son has the eternal function of submission to the Father
A self-proclaimed confessionalist: HERETIC!
Cornelius Van Til: The Trinity is one person and three persons.
A Self-proclaimed confessionalist: What a great man of God and a true defender of the faith!
Thus says the Lord:
Why do you see the speck that is in your brother's eye, but do not notice the log that is in your own eye? Or how can you say to your brother, ‘Let me take the speck out of your eye,’ when there is the log in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother's eye. (Mt. 7:3-5)
NOTE: I do not think Van Til is a heretic (but he is wrong), and I likewise do not hold EFS proponents to be heretics; this is just a reductio ad absurdum argument against the heresy hunters.
