Sorry, but you are incorrect. You even posted a verse that shows the church was future Matt. 16.
Paul said entrance into the church was through spirit baptism and that did not happen until Pentecost as Jesus said.
John 14:17
Even the Spirit of truth; whom the world cannot receive,
because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with
you, and
shall be in you.
Luke 24:49
And, behold, I send the promise of my Father upon you: but
tarry ye
in the city of
Jerusalem, until ye be endued with power from on high.
