He was very strictly orthodox and did not approve of gentiles. He did not allow any relaxation of strict observance of the law of Moses.
His miracles were his whole ministry. The performance of miracles are the signs performed by all who believe him, according to what he had said. So, if you are without any miracles, his miracles are the big problem.
His resurrection is the icing on the cake, it supports his gospel of the Kingdom of God, God’s power.
His followers reject most of what he was about, and fully embrace what Paul taught. So, I think Jesus might see this as the biggest problem…
Lord of the Sabbath
At the time Jesus went through the grainfields on the Sabbath. His disciples were hungry and began to pick some heads of grain and eat them. When the Pharisees saw this, they said unto him, Look! Your disciples are doing what is unlawful on the Sabbath."
He answered, "Haven’t you read what David did when he and his companions were hungry? He entered the house of God, and he and his companions ate the consecrated bread - which was not lawful for for them to do, but only for the priests . . . I tell you that one greater than the temple is here. . . For the Son of Man is Lord of the Sabbath.
Going on from that place, he went into their synagogue, and a man with a shriveled hand was there. Looking for a reason to accuse Jesus, they asked him, "Is it lawful to heal on the Sabbath?’
He said to them, “If any of you has a sheep and it falls into a pit on the Sabbath, will you not take hold of it and lift it out? How much more valuable is a man than a sheep! Therefore it is lawful to do good on the Sabbath.”
Then he said to the man, “Stretch out your hand.” So he stretched it out and it was completely restored, just as sound as the other. But the Pharisees went out and plotted how they might kill Jesus.
Obviously, Jesus and the Pharisees (as well as yourself) differed on what an observant Jew was and is, I think it all comes down to how Jesus interpreted the Mosaic law.
P.S. And if Jesus was very strictly orthodox, one has to wonder why the Pharisees (and the Saducees) wished to kill him.
