Rev. Wilson and the Cup

Doug Wilson is at it again. In a recent post about the Lord’s Supper he illustrates what is wrong with his view of the Supper.
First, Matthew 23:25-26 is not talking about the Supper. Thus, to apply this to the supper just because it mentions the word cup seems wrong headed.
Second, this sentence is just plain wrong. "When the Lord’s Supper is observed rightly, what is on the inside of the cup? It is the blood of Christ, the blood that cleanses from all sin."
It is not the blood of Jesus on the inside of the cup. It is wine. Unless one believes in transubstantiation it is always wine on the inside of the cup. The wine symbolizes the blood, but it is still wine. He is right that only the blood cleans us from sin, but he specifically states that if the Supper is rightly observed that the inside of the cup is blood on the body is on the platter. This is Romanism, and after over a thousand years it is still wrong.
Third, he contradicts himself in this next paragraph.
"Cleansing the inside of the cup is not accomplished by introspection. Cleansing the platter is not brought about by self-accusation. Sinners can only be cleansed because Christ their Savior died—and at this meal, we are confronted with that reality. Christ bled. Christ was broken. This broken bread cleanses the platter. This shed blood cleanses the cup. Look to that reality and respond in faith."
Note in this paragraph he says it is only the reality of the death of Christ that makes us clean. And that reality is not in our cup (admitting that the cup is only wine). That is much better, but does contradict what he said in the paragraph right before. He also seems to be confused about the benefit in the meal. He wants to deny it is benefit from mental activity, so he states it is not from introspection. Then he admits the benefit is only found in looking to Jesus, which is not actually in the cup. Thus, benefit can only be derived from a mental activity, the one of faith. "Look to that reality and respond in faith" is what the meal is supposed to do. Remind us the death of Christ. In faith, we can be strengthened through our remembrance of Him. But, the whole point of this post by Wilson is to say what is inside the cup cleans us. That cannot fit with "look to that reality and respond in faith."

Wilson tries to have it both ways in this post. That is part of the problem with Rev. Wilson. He just wants it both ways. But two opposites cannot both be true.
