The following excerpt is taken from On the Passover, a sermon preached by Melito of Sardis in 170 AD.  Read the whole sermon here.

This one is the passover of our salvation. This is the one who patiently endured many things in many people: This is the one who was murdered in Abel, and bound as a sacrifice in Isaac, and exiled in Jacob, and sold in Joseph, and exposed in Moses, and sacrificed in the lamb, and hunted down in David, and dishonored in the prophets. . . .

But you were found not really to be Israel, for you did not see God, you did not recognize the Lord, you did not know, O Israel, that this one was the firstborn of God, the one who was begotten before the morning star, the one who caused the light to shine forth, the one who made bright the day, the one who parted the darkness, the one who established the primordial starting point, the one who suspended the earth, the one who quenched the abyss, the one who stretched out the firmament, the one who formed the universe, the one who set in motion the stars of heaven, the one who caused those luminaries to shine, the one who made the angels in heaven, the one who established their thrones in that place, the one who by himself fashioned man upon the earth. This was the one who chose you, the one who guided you from Adam to Noah, from Noah to Abraham, from Abraham to Isaac and Jacob and the Twelve Patriarchs.

This was the one who guided you into Egypt, and guarded you, and himself kept you well supplied there. This was the one who lighted your route with a column of fire, and provided shade for you by means of a cloud, the one who divided the Red Sea, and led you across it, and scattered your enemy abroad.

This is the one who provided you with manna from heaven, the one who gave you water to drink from a rock, the one who established your laws in Horeb, the one who gave you an inheritance in the land, the one who sent out his prophets to you, the one who raised up your kings.

This is the one who came to you, the one who healed your suffering ones and who resurrected your dead. This is the one whom you sinned against. This is the one whom you wronged. This is the one whom you killed. This is the one whom you sold for silver, although you asked him for the didrachma. . . .

Who is my opponent? I, he says, am the Christ. I am the one who destroyed death, and triumphed over the enemy, and trampled Hades under foot, and bound the strong one, and carried off man to the heights of heaven, I, he says, am the Christ.

Therefore, come, all families of men, you who have been befouled with sins, and receive forgiveness for your sins. I am your forgiveness, I am the passover of your salvation, I am the lamb which was sacrificed for you, I am your ransom, I am your light, I am your saviour, I am your resurrection, I am your king, I am leading you up to the heights of heaven, I will show you the eternal Father, I will raise you up by my right hand.

This is the one who made the heavens and the earth, and who in the beginning created man, who was proclaimed through the law and prophets, who became human via the virgin, who was hanged upon a tree, who was buried in the earth, who was resurrected from the dead, and who ascended to the heights of heaven, who sits at the right hand of the Father, who has authority to judge and to save everything, through whom the Father created everything from the beginning of the world to the end of the age.

This is the alpha and the omega. This is the beginning and the end–an indescribable beginning and an incomprehensible end. This is the Christ. This is the king. This is Jesus. This is the general. This is the Lord. This is the one who rose up from the dead. This is the one who sits at the right hand of the Father. He bears the Father and is borne by the Father, to whom be the glory and the power forever. Amen.
