Can we not interpret the baptism of Jesus as a necessary act of repentance from the power inherent to his share in positions of structural authority (male, healthy, intelligent, etc.). It is by those powers individuals are able to move and shift along with culture as it continues to position itself in safety and security (by the exclusion and exploitation of others). Was this not a sin that needed repenting of so that he would live only as a child of God, grounded in an identity of love and acceptance so that he could live as such with his neighbour? Isn’t true repentance (of sin) the greatest testimony of his sinlessness? Just asking.
