“And there are three who give testimony in heaven, the Father, the Word, and the Holy Ghost. And these three are one.”
[1 John 5:7]
“And there are three that give testimony on earth: the spirit, and the water, and the blood: and these three are one.”
[1 John 5:8]
The Trinity, an inscrutable doctrine unique to Christianity.
Inscrutable because it is one of many mysteries of our faith, inexplicable.
No one can adequately explain this mystifying Doctrine, The Father, The Son and Holy Ghost yet; all three are one; except to say you can’t have one without the other.
One little analogy might be the Traditional Latin Mass of all times. Ponder on the definition of another mystifying term “Time,” think of the Mass as the past, present, and future for without it the world will end I fear.
Below is the text of the Nicene Creed the Profession of Faith which states the major truths of the Church, composed at the Council of Nicaea in 325. It was the answer to the Arian FALSE teaching that Christ was not divine.
I believe in one God,
the Father almighty,
maker of heaven and earth,
and of all things visible and invisible.
I believe in one Lord, Jesus Christ,
The only-begotten Son of God.
Born of the Father before all ages.
God of God, Light of Light,
True God of true God.
Begotten not made,
Of one substance with the Father.
By Whom all things were made.
Who for us men and our salvation came down from the heaven.
And He became flesh by the Holy Ghost of the Virgin Mary:
and was made man.
He was crucified for us, suffered under Pontius Pilate, and was buried.
And on the third day, He rose again, according to the Scriptures.
He ascended into heaven and sits at the right hand of the Father.
He will come again in glory to judge the living and dead.
And of His kingdom, there will be no end.
And I believe in the Holy Ghost, the Lord, and Giver of life,
Who proceeds from the Father, and the Son is adored and glorified
who spoke through the prophets. And one holy Catholic and apostolic Church. I confess one Baptism for the forgiveness of sins. And I await the resurrection of the dead. And the life of the world to come. Amen
