OK, mrgrumpy
Refuting the trinity is for lack of understanding.
The view in that site is from a humanistic understanding and lacks the spiritual side of understanding.
I understand the trinity view completely and have no problem with any verses that to man seem controversial.
The bible is designed to confuse in order for mankind to try harder to seek out the truth.
When mankind or folks such as your self who onces graced the pages of the bible with interest, became confused.
But rather than trying harder to seek out understanding, gave way to the easier path, and that is unbelief.
Why climb a mountain if there are so many obstacles in the way? Unless one has the hearts desire to reach the top, the obstacles are but a challenge and the going ruff, but at the top is victory over all of it.
Victory is not won standing on the sidelines of life, the easy path, the valleys, but in overcoming the challenges set forth in front of us so that onces the goal is met, we will have learned to conquer life in understanding.
PRO 24:3 Through wisdom is an house built; and by understanding it is established:
PRO 24:4 And by knowledge shall the chambers be filled with all precious and pleasant riches.
Knowledge of the wisdom of God is established by understanding, and the riches there in can only be known by understanding.
Here is wisdom, know and understand the word of God, and His riches will be yours.
