A. The Unchangable Law

According to Matthew 5:18, Jesus said that not the tiniest bit of the Law could be changed. However, in Mark 7:19 Jesus declares that all foods are clean, thereby drastically changing the Law.

The church tries to get around this obvious contradiction by artificially separating the Mosaic Law into the "ceremonial" law and the "moral" law, a separation which would have abhorred the Jews of Jesus' time. The Mark passage and similar ones like Acts 10:9-16 were added to accommodate the teaching of Paul regarding the Law (which was diametrically opposed to the teaching of Jesus on the Law) and to make the gospel palatable to the Gentiles.

 B. No Signs, One Sign, Or Many Signs?

At one point the Pharisees come to Jesus and ask him for a sign.

1. In Mark 8:12 Jesus says that "no sign shall be given to this generation."

2. In contradiction to Mark, in Matthew 12:39 Jesus says that only one sign would be given - the sign of Jonah. Jesus says that just as Jonah spent three days and three nights in the belly of the whale, so he will spend three days and three nights in the heart of the earth. Here Jesus makes an incorrect prediction - he only spends two nights in the tomb (Friday and Saturday nights), not three nights.

3. In contradiction to both Mark and Matthew, the gospel of John speaks of many signs that Jesus did:

a. The miracle of turning water into wine at the wedding in Cana is called the beginning (or first) of the signs that Jesus did (John 2:11).

b. The healing at Capernaum is the "second sign" (John 4:54).

c. Many people were following Jesus "because they were seeing the signs He was performing" (John 6:2).

 C. Son of David?

Matthew, Mark and Luke all contain passages which have Jesus quoting Psalm 110:1 to argue that the Messiah does not need to be a son of David (Matthew 22:41-46, Mark 12:35-37 and Luke 20:41-44).

1. This contradicts many Old Testament passages that indicate that the Messiah will be a descendant of David. It also contradicts official church doctrine.

2. In Acts 2:30-36 Peter, in what is regarded as the first Christian sermon, quotes Psalm 110:1 in arguing that Jesus was the Messiah, a descendant of David.

 D. The Fig Tree

After Jesus' triumphant entry into Jerusalem a sees a fig tree and wants some figs from it. He finds none on it so he curses the tree and it withers and dies (Matthew 21:18-20, Mark 11:12-14, 20-21).

1. Since this occurred in the early spring before Passover, it is ridiculous of Jesus to expect figs to be on the tree.

2. Matthew and Mark cannot agree on when the tree withered.

a. In Matthew, the tree withers at once and the disciples comment on this fact (Matthew 21:19-20).

b. In Mark, the tree is not found to be withered until at least the next day (Mark 11:20-21).
