RN 7-You do not even have faith there is a God, and you want to teach doctrine?
I don't believe you have the ability to read Kosta's his heart at all. Furthermore, Kosta KNOWS the correct teaching on the Trinity which means he is walking in truth,which means he is in the spirit of our Lord. Hersey is NOT of the Spirit of our Lord regardless of ignorance
Here is a good lesson for you to learn regarding the Trinity from Blessed Saint Gregory Nazianzen's Oration 31
"If ever there was a time when the Father was not, then there was a time when the Son was not. If ever there was a time when the Son was not, then there was a time when the Spirit was not. If the One was from the beginning, then the Three were so too. If you throw down the One, I am bold to assert that you do not set up the other Two. For what profit is there in an imperfect Godhead? Or rather, what Godhead can there be if It is not perfect? And how can that be perfect which lacks something of perfection? And surely there is something lacking if it has not the Holy, and how would it have this if it were without the Spirit? For either holiness is something different from Him, and if so let some one tell me what it is conceived to be; or if it is the same, how is it not from the beginning, as if it were better for God to be at one time imperfect and apart from the Spirit? If He is not from the beginning, He is in the same rank with myself, even though a little before me; for we are both parted from Godhead by time. If He is in the same rank with myself, how can He make me God, or join me with Godhead?"-Saint Gregory Nazianzen's Oration 31
And......
"They then who are angry with us on the ground that we are bringing in a strange or interpolated God, viz.:—the Holy Ghost, and who fight so very hard for the letter, should know that they are afraid where no fear is; and I would have them clearly understand that their love for the letter is but a cloak for their impiety, as shall be shown later on, when we refute their objections to the utmost of our power. But we have so much confidence in the Deity of the Spirit Whom we adore, that we will begin our teaching concerning His Godhead by fitting to Him the Names which belong to the Trinity, even though some persons may think us too bold. The Father was the True Light which lightens every man coming into the world. The Son was the True Light which lightens every man coming into the world. The Other Comforter was the True Light which lightens every man coming into the world. Was and Was and Was, but Was One Thing. Light thrice repeated; but One Light and One God. This was what David represented to himself long before when he said, In Your Light shall we see Light. And now we have both seen and proclaim concisely and simply the doctrine of God the Trinity, comprehending out of Light (the Father), Light (the Son), in Light (the Holy Ghost). He that rejects it, let him reject it; and he that does iniquity, let him do iniquity; we proclaim that which we have understood. We will get us up into a high mountain, and will shout, if we be not heard, below; we will exalt the Spirit; we will not be afraid; or if we are afraid, it shall be of keeping silence, not of proclaiming."-Saint Gregory Nazianzen's Oration 31
It's a good idea for us all to keep this in mind when we write about the Trinity so not to fall into error.
But they do make good chocolate!
