Arias began to deny the divinity of the Son of God and His oneness in essence with God the Father. The entire Church rose up against him; all believers, from all ends of the earth, unanimously confessed that the Lord Jesus Christ is the Only-Begotten Son of God, true God of true God; begotten, not made, of one essence with the Father.
One would think that this agreement was purely coincidental, but this faith was then tried by fire when the authorities and powerful of this world began to side with the Arians. Neither fire, nor sword, nor persecution could extinguish this faith, and it was immediately found everywhere among everyone, as soon as the pressure from external powers ceased. This means that it is the heart of the Church and the essence of its confession.
Glory to the Lord, Who preserves this faith within us! For, as long as it exists, we are still Christians, though we may not live as such. If it ceases to exist, Christianity ends.
