No, Jesus did not call the mainstream god Satan. And the Bible is not a jumbled mix of unrelated writings. It is a cohesive history of the Jewish people who had made a covenant with God to be His people, and He would bless the whole world through them. Which He did when Jesus was sent by God, and who fulfilled all the prophecies that had been given in scripture.

Jesus called out the hypocritical religious leaders of the time as followers of satan because they had perverted true word of God ( who Jesus called His Father) and true worship into mere legalistic ritual. The leaders were interested in personal power and money instead of repentant, obedient love for God.
