Upthread you.mentioned the need to differentiate between Jesus's intentions and the intentions of the gospel writers.
Would you be able to provide an example or two?
In the Q pericope on loving your enemies (Matthew 5:43-48 // Luke 6:37-36) there is a major difference between Matthew and Luke:
"Be merciful as your heavenly Father is merciful (Luke 6:36)."
"Be perfect as your heavenly Father is perfect (Matthew 5:48)."
Which is the original version of the saying? Well, in copying Mark, Matthew injects the demand of perfection where it is absent from Mark:
For example, consider the story of the rich young ruler:
"Jesus...said, "YOU LACK ONE THING; go, sell what you own and give the money to the poor, and you will have treasure in heaven; then come, follow me (Mark 10:21)."
"Jesus said to him, "IF YOU WISH TO BE PERFECT, go, sell your possessions, and give the money to the poor, and you will h;ave treasure in heaven; then come, follow me (Matthew 19:21)."
So scholars conclude that Luke's version of Q ("Be merciful..." is more original than Matthew's "Be perfect."
Then consider a second Matthean change of Mark in the story of the rich young ruler:
"As He was setting out on a journey, a man... asked Him: "GOOD TEACHER, What must I do to inherit eternal life?"Jesus said to Him: "WHY DO YOU CALL ME GOOD? No one is good but God alone (Mark 10:17-18)."
"Then someone came to Him and said: "TEACHER, WHAT GOOD DEED must I do to inherit eternal life?" And He said to him:" WHY DO YOU ASK ME ABOUT WHAT IS GOOD? There is only one who is good."
Matthew changes "Good teacher" to "Teacher" and "Why do you call me good?" to a question about the nature of goodness to remove the implication that Jesus denies both that He is good and that He is God. Jesus reserves the title "God" for "the Father" and believes that His goodness is derivative of the Father's goodness.
