1. Jesus, having come to the outskirts of Caesarea Philippi,  asked his disciples and said to them, “What do men say regarding the Son of Man? Who do they say I am?” They  answered him, “Some say you are John the Baptist; others, Elijah, others Jeremiah or one of the prophets.” Jesus said to them, “And you, who do you say I am?” Simon  Peter said to him, “You are the Christ, the Son of the living God.” Jesus responded  to him, “You are blessed, Simon, son of Jonah, because it was neither flesh nor blood that has revealed this to you, but my Father who is in heaven.” (Mt. 16:13-17; Mk. 8:27-30)

2. Meanwhile, when Herod the Tetrarch heard about everything that Jesus was doing, his spirit was perplexed, because some were saying that John had come back to life from among the dead; others that Elijah had appeared, and others that one of the ancient prophets had come back to life. Herod then said, “I had John beheaded, so who is this of whom  I have heard such great things?” And he desired to see him. (Mk. 6:14-15; Lk. 9:7-9)

3. (After the transfiguration) His disciples asked him, saying “Why, then, do the scribes say that it is necessary for Elijah  to come first?” But Jesus answered them, “It is true that Elijah must come and reestablish all things. But I declare to you that Elijah has already come, and they did not recognize him, but treated him as they wished.  It is likewise  that they shall cause the Son of Man to suffer.” Then his disciples understood that it was John the Baptist about whom he had spoken to them. (Mt. 17:10-13; Mk. 9:10-12)
