It is manifest that a dogma so mysterious presupposes a Divine revelation. When the fact of revelation, understood in its full sense as the speech of God to man, is no longer admitted, the rejection of the doctrine follows as a necessary consequence. For this reason it has no place in the Liberal Protestantism of today.

Any group that denies the Trinity cannot be considered Christian, let alone Protestant. As your article points out, the scriptures are filled with evidence. To deny the Trinity is to not understand the Word of God.

Both sides can be civil and I believe (as a Trinitarian) that we can demonstrate adequately well, so that those confused can arrive at a conclusion
