PROLOGUE The year of 1866 designates the beginning of an era of light, the Third Era. Elijah, the prophet, came spiritually to remove the veil of mystery and introduce the period of God's communication with mankind as the Holy Spirit. Elijah illuminated a man destined by the Father to be the forerunner. That chosen one, named Roque Rojas, was he who listened from spirit to spirit to the voice of the prophet, who ordered him in the name of the Father to call and unite his brethren, because a Divine revelation was about to illuminate the destinies of humanity. Roque Rojas, gentle and humble as a lamb, obeyed the spiritual voice, answering: "God's will be done upon me." Roque Rojas assembled a group of men and women of faith and good will, and there, in the midst of his first gatherings, Elijah manifested himself through the human understanding of the Envoy saying: "I am Elijah, the prophet, the same of the transfiguration on Mount Tabor." He gave instructions to the first disciples, at the same time that he proclaimed to them the era of Spirituality and he prophesied that the Ray of Light of the Divine Master would communicate with His people soon. On a day when the humble dwelling of Roque Rojas was full of faithful followers who believed the word of that man, Elijah descended to illuminate the mind of his spokesman, and inspired by the Holy Spirit, he anointed seven of those believers to whom he gave the representation or symbolism of the Seven Seals. Later, when that promised moment of the communication of the Lord took place, from those seven chosen, only one kept vigilance awaiting the arrival of the Pure Spouse and that heart was that of Damiana Oviedo, the maiden whose human understanding was the first to receive the light of the Divine Ray as a reward for her perseverance and her preparation. Damiana Oviedo represented the Sixth Seal. It was one more proof that the light of the Sixth Seal illuminates this era. During the Second Era the Word found a woman's endearing reception, a maternal love, and during this era, the promised lightning that came out of the east unto the west rested in the chaste and pure heart of Damiana Oviedo. Her maidenly tenderness was maternal for the people of Israel and through her guidance the Lord prepared the guides, spokesmen and laborers. The Third Testament are the abridged texts taken from transcriptions of revelations received in Mexico during the middle of the past century until 1950. Those revelations told men that a new era of spiritual enlightenment had come, and that The Advent of the Lord was truly a reality. I come in spirit during this era. My light descends upon man like tongues of fire, so that they will be able to speak of My law in all languages. 144000 incarnated and discarnated spirits will open the way during this period. They will be forerunners, prophets, and messengers. They are the ones marked by Me to go before the multitudes. To these chosen ones there will be revealed the name of the tribe to which they belonged during the First Era, so that they may realize that since then, they made a covenant with their God, and have followed the path of the Father long ago; but during this period all names of the tribes have disappeared, for it is not the Lord who sets boundaries to divide men. Your presence before this manifestation has not been by chance. My voice summoned you along the pathways and guided you here. Now you know that you have come to recognize the mission that you have to fulfill on Earth. In My word you shall learn what is your beginning and what is your ending. You have had the revelation that you are a part of the people who have received the manna of the spirit during three eras.
