The Temple's veil

Matthew and Mark both discuss the prodigies occurrent upon the death of Christ. I'd look at Mark 15:38. Here, the καταπέτασμα in the Temple was ἐσχίσθη.

Matthew 27:51 also has the tearing of the veil in these exact words; John 19 has nothing between vv. 30 and 31 (but as I keep saying I think John is developing a primitive Passion, not reacting to the Synoptics). Matthew here offers convulsions from Earth to Heaven, between the dead and the living. That's what the veil represents, for this our most Jewish-Christian Evangelist.

Those who call v. 38 an interpolation into Mark 15, besides The Greisbach Bro's, would say that versions of Mark were doing some harmony with Matthew. Mark after all suffered a Thomas-tier weak transmission-record until the third AD century; maybe some copyist felt a need to boost Mark a little, in order to have this Gospel copied at all.

I counter-propose. Back in Mark 14:63-4 the high priest has theatrically rent (διαρρήξας) his own robes as to accuse Christ of "blasphemy". Then beneath the Cross the people "blaspheme" Christ 15:29. At Mark 15:33 the sky darkens. Verse 38 thus presents the suffering and death of Christ as the true blasphemy, to which G-d rends His robe.

As for Matthew, I don't need to credit Mark himself with being this clever at v. 38. If the text were interpolated early-enough, it makes no difference to Matthew who then found it in his text. He'd already read that Darkness At Noon. To vv. 33 and 38 both, Matthew 27's shuddering of the Earth and shaking of her graves represents a midrash.

But I do think Mark was this clever. The question moves to: what Christian would remove this verse, given its backup in Matthew. I suggest such a one as didn't accept the Temple as the House of the Lord, ever. There were Christians - not just Marcionites - who scorned the Mount and demanded it be kept in ruins. So: John?

CORRECTION 4/13: An early version confused this with v. 28, lately pdf. Sigh. Well, at least the overall argument can stand, as a support for Marcan priority if naught else.
