Jesus did make a point, in his use of metaphor, when he claimed his disciples as his "brother and sister and mother" (Matt. 12:49-50) while at the same time acknowledging God and God alone as his Father. To some extent, this description of the relationship between Jesus and the Father is intended to convey Jesus' miraculous conception, but more than that I think it is intended to convey an eternal relationship within the godhead, between Father and Son, a relationship of love and cooperation, of authority and submission, of will and obedience. That didn't begin with Jesus appearance on earth, but is an eternal aspect of the nature of Father, Son, and Spirit, which is also intended to affect our relationship with God and our relationships with other people, revealing a need for order and authority and submission within love.
