Category 1. Separate events occurring at different times. For example there are three reports of a husband pretending that his wife is a sister, twice by Abraham and once by Isaac. Notwithstanding close similarities in these reports they are held to be different events.
Category 2. Words not uttered under Divine inspiration. The principle here is that only the actual writers of the books of the Bible were divinely inspired. These writers may report statements made by others, but the inclusion of such statements does not necessarily mean that they are true. The application of this concession is very arbitrary, and is not extended to the Gospels or to Acts.
Category 3. Differences in the standpoint of the writers, or of writer and reader. From a physical standpoint one writer may say that man is mortal, while another, writing from a spiritual standpoint can say that man is immortal. The explanation is sometimes reasonable, but is often abused.
Category 4. Different methods of arrangement. A number of discrepancies can be made to disappear if it is assumed that the writer is not maintaining true chronological order, or is condensing his narrative by grouping similar incidents, or omitting incidents that he considers have no direct relevance. Such assumptions too often appear to have no justification.
Category 5. Different ways of calculating dates and times, and numbers. In Hebrew reckoning any part of a day was counted a whole day, and any part of a year as a whole year. Hence the Bible can say that Christ rose on the third day where by modern reckoning he rose on the second day. Also it is known that in Christ's time two different calenders were in use, civil and sacred. In regard to the improbably large numbers that often appear it is claimed that Hebrew allows numbers to be written in reverse order. This claim is not generally accepted.
Category 6. Oriental style and idiom. Allowance must be made for middle-Eastern style, which employs a much greater degree of fanciful hyperbole and exaggeration than we would consider acceptable in a historical record. It cannot be termed a discrepancy where Psalm 91 speaks of God as having wings and feathers.
Category 7. Plurality of names. A single individual may be referred to by many different names. For example the Apostle Peter is also called Simon, Simeon, Cephas, Simon Peter, Simon Bar-jonas, and Simon son of Jonas. Further the names of people and places not infrequently were changed, commonly to mark some important event.
Category 8. Different meanings of the same word. It often happens that the same English word is used to translate a number of Hebrew or Aramaic words having substantially different meanings; conversely a single Hebrew or Aramaic word may have many English meanings - the result may be that the translation is untrue to the original.
Category 9. Copying errors. Several letters in the Hebrew alphabet are very similar to others, for example Beth and Kaph, Daleth and Resh. It would be easy, even inevitable, for a careless copyist to make some mistakes, while other copying errors can also occur. This explanation can be acceptable where a specific error is occasional and random, but not where it is common or systematic.
Category 10. Critic's imagination. This is the largest group - where some critic imagines there is a conflict which does not in fact exist. The author's judgement here is usually sound and acceptable.
Acts 1:18 "Now [Judas] purchased a field with the wages of iniquity; and falling headlong, he burst open in the middle and all his entrails gushed out.
Mat 27:5 "Then he threw down the pieces of silver in the temple and departed, and went and hanged himself." Matthew goes on to say that the priests bought a field with the money, for use as a burial ground.
Num 22:20 "If the men come to call you, rise and go with them . . . So Balaam rose in the morning, saddled his donkey, and went with the princes of Moab".
Num 22:21 "Then God's anger was aroused because he went"
1 Sam 15:3 "Now go and attack Amalek, and utterly destroy all that they have, and do not spare them. But kill both man and woman, infant and nursing child . . ."
1 John 4:16 "God is love"
Num 16:31-33 says that Korah and all those with him were swallowed by the earth.
Num 16:19 and 35, Psa 106:18, say that the whole group were burned.
Mark 1:23-24 says that a man with an unclean spirit identified Jesus as 'The Holy one of God'.
1 John 4:1-2 says that anyone who confesses that Jesus has come in the flesh is of God.
Matt 9:24-25: Jesus is told that a girl is dead, but replies that she is only sleeping. She rises when he takes her hand.
Jer 25:27 says "Drink, be drunk, and vomit! . . ." The claim is made that God is contributing to the social evil of drunkenness. Reading the context shows the absurdity of this.
