As my kids used to say yeah huh. The Church did exist from all eternity, because the Church is Jesus, and the Church is God, and Jesus and God and the Church are all part of the Trinity. The Church is the last Part of the Trinity the Holy Spirit.
And the Church is the Person of Christ. There is the Father which was revealed in the word, the Son which was revealed in Jesus, and the Holy Spirit which was and is still revealed in the Catholic Church.
Let me say this in a different way. When Jesus said Saul why are you persecuting me how could Saul be persecuting Jesus he was already in heaven???
If someone kicked you in the arm, your whole body shares in the pain.
What Christ was telling Saul was in striking his Body Saul was striking HIM.
When the Body of Christ was persecuted it was Christ the invisible head who spoke to saul.
Therefore the Mystical body of Christ no more stands between Christ and an individual then his physical body stood between Magadalen and his forgiveness.
It was his human body that came to men in the individual life, but it is his Mystical body or HIS CHURCH that comes to men in the Mystical life.
It was the N.T that came out of the Church not the church out of the N.T.
The body had 4 marks. unity, (which is why I said that the Father the Son and the Holy Spirit are all made up of one GOD.) IT has one SOUL, one Spirit.
It is unity that keeps the Church as one Which is what Catholicity is.
The third is Holiness which is our promise that the Church will keep itself health and pure and free from heresy.
And divine, because it is by the gift of the Holy SPirit.
ANd Apostolic because it has its roots from Christ.
But the Church is still Christ walking around in the Mystical Body instead of his Human body is all.
What I am saying is the Church is still Christ, and Christ is one in being with the Father. The Trinity is the Father, the Son and the Holy Spirit made up of ONE GOD. Just like Christ is the Church, Christ is also God made Man. They are all part of one another.
It is in the form of the Holy Spirit that instead of the Human Form of Christ that the Church is being led. BUt it makes no difference.
But regardless the CHurch is still led by God and not apart from God because all things come from God. Rather it is in the name of the Father the Son or the Holy Spirit it is still ONE GOD. All are led by ONE God, all one in being with the Father. God from God, light from light, True God from True God. which all things were made.
It does not matter if it is the Mystical Church, or Christ here in the Human it all stems from one source GOD. That is what Unity is. As the Father SOn and HS are in unity we are to be one in unity also with the Living CHurch here on earth which is the CC.
Just like you can’t take God from the Father, and the Father from the Son, and the Holy Spirit its all one. There is only ONE GOD leading the Church. No matter what power he exercises it through. That was my point!!
