Amen to that; however, while it is a sacrament in the Catholic church, it is merely a "covenant" in the Protestant realms. This shocking fact, along with several others, greatly weakened my loyalty to the Protestant church of my upbringing. Among Protties, there are only three sacraments: communion, baptism, and confirmation. It boggles the mind, really, that the ordination of pastors is not even considered, much less leaving out marriage, which Christ said is like unto His relationship to the Church.
But a Sacrament is when the Word is joined to a material object for the explicit purpose of delivering God's grace and forgiveness to the recipients. I don't see how marriage is a Sacrament in that case, because it doesn't deliver forgiveness of sins. Nor is ordination, because it doesn't deliver forgiveness of sins.
