c.c.c.82. "As a result the church, to whom the transmission and interpretation of Revelation is entrusted, 'does not derive her certainty about all revealed truths from the holy Scriptures alone. Both SCRIPTURE and TRADITION must be accepted and honoured with equal sentiments of devotion and reverence.
Is a lie.
The Bible presents the Trinity so directly that only willful blindness allows you to claim it isn't there.
I JOHN 5:6 ¶ This is he that came by water and blood, [even] Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.
I JOHN 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
I JOHN 5:8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.
I JOHN 5:9 If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.
GENESIS 1:26 ¶ And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
GENESIS 1:27 So God created man in his [own] image, in the image of God created he him; male and female created he them.
GENESIS 1:28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
As expected you make the pitch for your cult's continual quest for control.
So, if scriptural proof texts are inadequate to prove the doctrine of the Trinity as you and I accept it, then what authority DID define the doctrine of the Trinity as you and I understand it. It clearly is NOT clear from a reading of scripture alone.
Since you reject the Holy Bible which God inspired to be written, what then is the authority of your roman cult based on?
A few true words from you. That is rare these days.
This has been the standard of Christianity from the very start 2000 years ago. A little less than 500 years ago a few men came along with a new false gospel, called Sola Scriptura, that they used in their revolt against the order and authority Christ ordained for His Church.
but I am certain there are no Christians who are truly "catholic".
...but I am certain that only a person demonically deceived would make such an evil generalization.
Since said "roman cult" determined which books should be included in the Bible, what leg do you have to stand on?
