Jesus came from Galilee, a region populated by farmers. He was likely uneducated, having been a labourer until that point. Yet after His reappearance from the wilderness, the change must have been startling to everyone who knew Him. Miracles started happening, the first of many being at the marriage of Cana. He began to gain a following.
Jesus also began to teach, something only the Pharisees had official designation to do. It must have raised eyebrows because Jewish civil and ecclesiastical law were nearly the same at the time. Jesus was teaching crowds outside the synagog and healing the sick and afflicted outside the temple - and without the prescribed ordinances.
Jesus didn't ask for permission, He didn't need to. He authorized Himself.
