Tertullian

For when you do not deny that the Creator's Son and Spirit and Substance is also His Christ, you must needs allow that those who have not acknowledged the Father have failed likewise to acknowledge the Son through the identity of their natural substance; for if in Its fulness It has baffled man's understanding, much more has a portion of It, especially when partaking of the fulness Now, when these things are carefully considered, it becomes evident how the Jews both rejected Christ and slew Him; not because they regarded Him as a strange Christ, but because they did not acknowledge Him, although their own.
