No, there is no need for any priesthood, Levitical or Aaronic. (Heb.7-9).
All believers are now Priests (1Pe.2:5)
Our High Priest is Christ Himself (Heb.10)
2, If the prophecies of the ressurection had not been fullfilled there is now way Christ could be considered the messiah testified to in the Old Testament.
Yes, but the Resurrection was going to happen, thus the rending of the Temple curtain from top to bottom.
Also the only scripture i can find which mentions the repentant thief is Luke which is abiguous as to when the good thief died.
Nothing ambiguous about it.
John 19 described the fact that the soldiers broke the legs of the thieves to hasten their deaths, but when they came to Christ they didn't have to,seeing He was already dead.
That is one of the soldiers stuck the spear into him (Jn.19:32-34)
you’re ignoring that John never spoke of any theives repenting.
we hold to Christ being the high priest btw. actually from 1 peter 2:5 i can see that there is a house and a priesthood i do not see where everyone in the house is automatically in the priesthood, Hebrews seems to specifically do away with the Levitical priesthood but does not seem to do away with priesthood at all but rather change it.
