Indeed, his words "Call no man on earth your father, for you have one Father, who is in heaven" may very well be directed against the patriarchal family, which as the primary social unit in that world was a microcosm of a hierarchical system. If so, this is a fascinating instance of Jesus using the image of God as Father in a way that subverted patriarchy. (82, Marcus Borg, Meeting Jesus Again for the First Time)
