The Secret Chapters

Chapter 53 in the Book of Yisayahu is not a secret or hidden chapter. The Chapter is clearly speaking about the Prophet himself.
There are secret, in the sense of overlooked, verses, however, that all the Rabbis ignore. They are: Yishayahu 60:1-2 and 21 and Chapter 4 in the Prophet Micah, the Prophet Yishayahu's contemporary. In those passages it is clear that HaMashiach is Female - not just one particular Female, but Jewish Femininity is its full bloom. That is what neither the Rabbinic heresy or it's disowned bastard child, the Christian heresy can accept.
Both of your heresies are locked in battle because neither of you can accept the Torah Truth.
