Except I'm not a Catholic.
The reality is that I have leanings towards Oneness Pentecostalism.
The blood is in the water (1 John 5:8).
Good, and I will let you believe that you don't need to be baptized in water (even though it could be to your eternal destruction).
So, I take it this conversation is finished?
I will say this: that a careful comparison between Acts of the Apostles 2:38-39 and Romans 8:30, with a view to the application of the word "called" ought to bring you to a specific point of view.
There are some things in this post and others you have posted that must be refuted in the name of Christ!
In 1 John 5:8, you are mistaken my friend! No hard feelings toward you, but this must be clarified.
In vs 7 John tells us there are three that bear record in heaven, the Father, the Son, and the Holy Spirit, these three are one.
In vs 8 John tells us there three that bear record in EARTH, the Spirit, the water, and the blood, these AGREE in one.
What are they agreeing on? vs 9, "for this is the witness of God which He has testified of His Son."
They are witnessing here on earth that Jesus Christ is the Son of God, the Saviour of the world! How do they do this?
They do it by the Holy Spirit, by the water, and by the blood! What does this mean?
Jesus laid aside His power as God and was lead totally by the Holy Spirit, all the miracles performed by Christ were done by the Holy Spirit witnessing that Jesus is the Son of God, the Saviour of the world, and He did it with great power as a witness on this EARTH.
The water is the witness that Jesus is the Christ! The water symbolizes His incarnation, being born a man just a we are. The prophets declared He would come as a man to save His people from their sins. The water, being born as a man is a witness on this EARTH, that He is the Christ.
The blood that He spilled at Calvary's Cross in a witness on this EARTH that He was the Christ. All the animal sacrifices of the Law of Moses pointed to the blood of Christ, as our Saviour.
