Yes it's being completely controlled in Rome and all the rules and definitions are made there. The bible calls for Elders to lead churches but Rome makes up a brand new thing, a Christian Priest, completely foreign to the bible. Everything from that wrong definition is going to be wrong so there is no wonder that they go astray.
Rome has steppd in only because of the American episcopacy's failure to address the problem. Even so most of these problems have been dealt with at the diocesan level. Appeal is made to Rome per canon law when victims (or the accused) feel that the diocese has dropped the ball.
But as for priests, those are in fact trained and accepted at the diocesan level. Even bishops are largely selected by cioceses in the region, with the Pope only formally approving their choices in most cases. With some 4,000+ Catholic dioceses worldwide, it is impossible to do it otherwise.

The idea of a sacramental priesthood is in evidence almost immediately in the early Church (Apostolic, post-apostolic patristic) writings - if they got it wrong, pretty much every early Christian community did, east and west.
Only when making an altar.
