My mind is my own church
Could it be that they are a collection of stories of metaphors and poems ?. And should not be taken in a literal sense. A mountain can mean many different things in Ancient languages. My intention is not to offend , but to apply logicAnd do you know anyone has made it to the top of this mountain? And learned this revelation? Why is it we have never heard of him or her but have heard about Christ rising from the dead to appear to many? Why didn't He talk about this supposed revelation, you'd think that since He came back from the dead, He of all people would've known about this supposed truth. Why do none of the "spiritual masters" of the Catholic Church talk about this, St. Teresa of Avila doesn't talk about this, St. Faustina doesn't mention this, the child-like St. Therese of Lisieux doesn't mention this, nor does St. John of the Cross who wrote a book called The Ascent of Mount Carmel! Our Blessed Mother despite being in Heaven and being Conceived without our fallen nature, also never mentioned this in Her apparitions on Tepeyac Hill, Lourdes, Fatima, and elsewhere.
Also "spiritual" simply refers to that which concerns our intellects and wills, we're all spiritual, we all have spirits, intellects and wills; religion by contrast refers to giving God His due, we simply refer to other beliefs and practices as such because they resemble this virtue.
