Tertullian

“ When Oshea the son of Nun was destined to be the successor of Moses, is not his old name then changed, and for the first time he is called [4] Joshua? It is true, you say. This, then, we first observe, was a figure of Him who was to come. For inasmuch as Jesus Christ was to introduce a new generation [5] (because we are born in the wilderness of this world) into the promised land which flows with milk and honey, that is, into the possession of eternal life, than which nothing can be sweeter ”

“ To this day, in short, it is Christ that they are looking for, not Jesus; and they interpret Elias to be Christ rather than Jesus. He, therefore, who came also in a name in which Christ was not expected, might have come only in that name which was solely anticipated for Him. [1] But since he has mixed up the two, [2] the expected one and the unexpected, his twofold project is defeated. For if he be Christ for the very purpose of insinuating himself as the Creator’s, then Jesus opposes him, because Jesus was not looked for in the Christ of the Creator ”

“ In short, there must now for the future be made between us that certain and equitable rule, necessary to both sides, which shall determine that there ought to be absolutely nothing at all in common between the Christ of the other god and the Creator’s Christ. ”
