According to Theodore Zahn, the article of faith up until about 250 AD was, "I believe in God, the Almighty." Between 180 and 210 AD the word 'Father' was added before 'the Almighty'. This was bitterly contested by a number of the leaders of the Church. Bishop Victor and Bishop Zephysius are on record as condemning this movement, since they regarded it an unthinkable sacrilege to add or subtract any word to the Scriptures.
