“to establish a Church that could be interpreted by anyone to mean whatever they think it to means by anyone who reads a bible”
On one hand it is not hard to say that that is exactly what the Roman Catholic Church has done in self-surving Roman Catholic theology that ascribes to itself and itself alone what a proper expression of Christianity is, in spite of many errors in that doctrine and practice.
But Yeshua never gave temporal authority to an institution of men - he gave his authority to individuals and it is to Him, not their human-made institutions (in which they may or may not have always lived up to Christ’s mandate to them) that they have always owed their worship - founding His Church on the rock of salvation of belief that He is the risen Christ, not on a temporal foundation of a human institution that only imperfect humans create.
Christ’s Church - the Church I just described - WILL continue to the end of time and humans will continue to participate in THAT church - a personal relationship with G-d, no matter how often scripture, their faith and the inspiration of the Holy Spirit leads them to end, alter, change and reform human temporal institutions that other humans built. Christ is not against that process, He is part of it, part of keeping his only real Church present among men - his spiritual Church, whether they claim to be part of this or that human institution, or not.
Makes no sense whatsoever. So everyone can make up what they want to believe.
What do these four words of Scripture mean - "This is My Body."
Does is (estin in Greek) mean is, or does it mean 'represemts' as so many believe? How do you know with certainty?
We know is means is because of the Church Christ established. You know it means represents because of man-made traditions and beliefs.
