Then you do not understand.
If you are validly baptized, you have accepted that God’s grace is working in you, and you are a member of the Body of Christ, as I am. That is one aspect of the Church
If you accept all that the Church reveals to you as Divine Truth (which I see that you have not), then Catholics would call you brethren, but separated brethren…still part of the Church.
In God’s time, He will call on you to come to Him totally, so that He can come to you totally… The Eucharist, the Real Presence is the fulfillment of His promise to “,be with you always…”
If we both walk toward the Lord, and follow as best we can in His footsteps, we will be together for eternity as full and fully accepting members of His One, True, Catholic and Apostolic Church… and I know you understand what that One Church is called here on Earth…
