We will give another illustration. The seed of last year is sown, branches and leaves grow forth, blossoms and fruits appear, and all has again returned to seed. When this second seed is planted, a tree will grow from it, and once more those branches, leaves, blossoms and fruits will return, and that tree will appear in perfection. As the beginning was a seed and the end is a seed, we say that the seed has returned. When we look at the substance of the tree, it is another substance, but when we look at the blossoms, leaves and fruits, the same fragrance, delicacy and taste are produced. Therefore, the perfection of the tree has returned a second time. In the same way, if we regard the return of the individual, it is another individual; but if we regard the qualities and perfections, the same have returned. Therefore, when Christ said, “This is Elias,” He meant: this person is a manifestation of the bounty, the perfections, the character, the qualities and the virtues of Elias. John the Baptist said, “I am not Elias.” Christ considered the qualities, the perfections, the character and the virtues of both, and John regarded his substance and individuality. It is like this lamp: it was here last night, and tonight it is also lighted, and tomorrow night it will also shine. We say that the lamp of this night is the same light as that of last night, and that it has returned. It refers to the light, and not to the oil, the wick or the holder. This subject is fully and clearly explained in the Kitáb-i-Íqán. 34: PETER’S CONFESSION OF FAITH Question.—In the Gospel of St. Matthew it is said: “Thou art Peter, and upon this rock I will build My church.”(117) What is the meaning of this verse? Answer.—This utterance of Christ is a confirmation of the statement of Peter, when Christ asked: Whom do you believe Me to be? and Peter answered: I believe that “Thou art the Son of the living God.” Then Christ said to him: “Thou art Peter”(118)—for Cephas in Aramaic means rock—“and upon this rock I will build My church.” For the others in answer to Christ said that He was Elias, and some said John the Baptist, and some others Jeremias or one of the Prophets.(119) Christ wished by suggestion, or an allusion, to confirm the words of Peter; so on account of the suitability of his name, Peter, He said: “and upon this rock I will build My church,” meaning, thy belief that Christ is the Son of the living God will be the foundation of the Religion of God, and upon this belief the foundation of the church of God—which is the Law of God—shall be established. The existence of the tomb of Peter in Rome is doubtful; it is not authenticated. Some say it is in Antioch.
