You see? That's the problem. What he had done was not "blasphemy" under Jewish law and the laws ARE complex. The writer didn't know themso he made stuff up based on his limited understanding. Instead of assuming that an entire legal structure is simplistic and was manipulated in one particular case, it makes more sense to say that the story teller was making errors.
Well, there is one opinion that they were written by Jews in order to create an origin story which made the Christian sect distinct from the Jewish sect. Scholars see the stories as dating to well after Jesus' supposed death so at best the content is hearsay, steps removed from the events depicted. So the narrative is reconstructed with details invented to satisfy an agenda.
His enemies considered it blasphemy weather it was or not. Being the Son of God incarnate then no, what he said was true and not blasphemy. But considering that the Jews didn't believe Jesus was the Son of God then yes, to them what he said was blasphemy.
One reason that the gospels weren't written for a while was the belief that Jesus would "soon return" . So word of mouth preaching and teaching worked until they decided to record what happened.
BTW, many of early the events depicted in Genesis were thousands of years after the fact and credited to multiple authors, but I'm assuming you have no problem believing them??? Double standard?
A: Jesus was “directly” accused of “blasphemy” on three different occasions, and “indirectly” accused on two more (they didn’t say Jesus had committed “blasphemy,” but they wanted to kill Him [the penalty for blasphemy] for proclaiming deity. Of course, we know that since
Jesus “IS” God (He has never stopped being God), and
He was sinless (
2 Cor 5:21)(
Heb 4:15)(
1 Jn 3:5)(
1 Pet 2:22), any accusations of blasphemy were false. Following are the five occasions.
#1. (
Mt 9:1-8)(
Mk 2:1-12)(
Lk 5:17-26) Jesus was accused of blasphemy by the scribes for telling the paralytic man that his sins were forgiven.
#2. (
Jn 10:30-33) The Jews accused Jesus of blasphemy, and were going to stone Him for “making Himself God.”
#3. (
Mt 26:63-66)(
Mk 14:61-64)(
Lk 22:67-71) The High Priest accused Jesus of blasphemy for claiming to be “the Christ, the Son of God.”
#4. (
Jn 5:17-18) (“indirect”) The Jews wanted to “kill” Jesus for saying “that God was his Father, making himself equal with God.”
#5. (
Jn 8:58-59) (“indirect”) The Jews were going to stone Jesus for calling Himself the “I AM.”
In addition, Jesus was accused of committing “sin” in several other places (
Jn 9:24)(
Mt 11:18-19)(
Lk 4:16-29)(
Lk 7:33-35). He was also called a “friend of sinners” several times (
Mt 9:10-13)(
Lk 7:36-50 – He forgave sins here too)(
Lk 15:1-3)(
Lk 19:7).
