Jesus cannot have believed that he was literally the Son of God. Yahweh does not have testicles.
On Jesus the Radical:
Some aspects of the way Jesus is presented in these texts have an obvious radical resonance. He is presented as a homeless, propertyless, peripatetic, socially marginal, disdainful of kinsfolk, without a trade or occupation, a friend of outcasts and pariahs, averse to material possessions, without fear for his own safety, a thorn in the side of the Establishment and a scourge of the rich and powerful. The problem of much modern Christianity has been how to practice this lifestyle with two children, a car and a mortgage.
