As for his healing, it indicates that the one who is healed from doubt—symbolized by sickness—is not obligated to maintain the Outward at all, except by necessity.

As for his saying to him: "See, you are well; sin no more, lest something worse happen to you," meaning: if you are veiled from the Inward or doubt it, then there shall befall you something greater than what afflicted you of the sickness—symbolized by doubt and being veiled (Hujba).

As for Jesus' saying to the Jews: "My Father is working until now, and I am working," it is an alert that the rejection of the Outward is by the will of Allah and His Messenger.

What is the evidence that in his era he was among the people of this esoteric religion?

As for his saying: "Truly, truly," meaning that the speech he says is the Truth and that he did not bring anything except as Allah the Exalted commanded him. This is because he is the most knowledgeable of them and of others regarding His intent for the Sabbath. He said to him: "I am the Lord of the Sabbath" so it would be confirmed and verified for them that he does not intend belief in the outward form of the Sharia.
