Tim Troutman has just published an article at Called To Communion. The article is titled "Holy Orders and the Sacrificial Priesthood." He writes:
At the heart of the separation of Catholics and Protestants lies a disagreement about the ecclesial hierarchy. Who are the rightful shepherds of Christ’s flock? This article will examine the Catholic Church’s doctrine of the sacrificial priesthood, and in doing so, will lay the foundation for our subsequent discussion on the critical issue of apostolic succession. We will argue for the following four claims. The hierarchical difference between the clergy and the laity was ordained by God and is supported by the Biblical data. The distinction between presbyters and bishops existed from apostolic times and was intended by Christ. Christian ministers are ordained into a visible priesthood that is distinct from the general priesthood of all believers. Finally, Holy Orders is a sacrament.
