There were no priests...how do you not get this?  I get so tired of folks who think that The Church arrived full-blown on the morning of the Resurrection or maybe at Pentecost... many things have evolved (oh, I know that is a dirty word because THE CHURCH HAS NEVER CHANGED - ) and grown and been left open to The Spirit and  will continue to change and grow and evolve in all Her Trinitarian splendor...if you don't feel comfortable with growth and change and, yes, evolving, then I guess you are not part of a church that is ALIVE...so you just crawl back in your cocoon and hug your dead church to yourself...we are ALIVE!!! Pope Francis knows this...some other hierarchical types just don't get it.
