A logical fallacy is to exclude knowledge which may help us know the Scriptures better. A good commentary gives insight from Bible experts. A lexicon helps us understand words in ancient Hebrew and Greek. Forming an opinion based merely upon one mediocre study source, such as an encyclopedia, is sloppy research. The logical mistake called the fallacy of exclusion means that we are missing vital facts. And because of this, we don’t really know the Scriptures.
Beginning in Matthew 22:23, some Sadducees tried to trap Jesus into stating his opinion without giving him the full story, excluding pertinent facts. Whose wife would a woman be in the resurrection if she had been married and widowed 7 times? The solution to this problem is the same with any fallacy of exclusion: fill in the missing information – there is no marriage in the resurrection. Jesus informed them of their fallacy: “Your mistake is you don’t know the Scriptures.” That’s what Jesus said.
