I'm wondering what your view is of the hierarchy that Jesus established. Why pick 12, why not all the disciples? Why not everyone a priest?
Hebrews 7:12 For the priesthood being changed, there is made of necessity a change also of the law.
1 Peter 2:3 If so be ye have tasted that the Lord is gracious.
4 ¶To whom coming, as unto a living stone, disallowed indeed of men, but chosen of God, and precious,
5 Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
