Today I read the following article on Matt 16:16-19 and its use of Isa 22. What is important about this article is that is provides further support for Jesus establishing an ordained/ministerial New Covenant Priesthood:
Michael Patrick Barber, "Jesus

Journal of Biblical Literature vol. 132, no. 4 (2013):935-53.
