I have come to a startling conclusion after reading two articles that I recently saw online, and that conclusion is that Protestants do not really worship God. I obviously have to qualify and clarify this statement, since it is a most serious charge, but it centers around the fact Protestants must admit that formal worship is a non-essential Christian teaching. If you stop and think about it, the fact is Protestants cannot agree on how or when Christians should worship, and unless a Protestant denomination wants to take a dogmatic stance, they're forced to take on the repugnant position that it doesn't really matter how or when (if ever!) a Christian should worship.
The first article I want to point you to is called "10 Reasons to be Involved in a Church." Before clicking on the link, just let the title of that article sink in. The impression given off is that while it is a good idea to be involved in a church, it is not something absolutely necessary. In fact, it comes off as seeking a church that suits your preferences, not some objective criteria by which all Christians should approach the issue. The article was written because the author claims only 8% of Protestants in Britain and only 40% of Protestants in America attend a church on Sunday. In other words, attending church is now seen as something purely optional to the Christian life. And this makes perfect sense with the "don't tell me how to be a Christian" mentality that Sola Scriptura causes. Not unsurprisingly, all 10 of his reasons are nothing more than suggestions, and none of his reasons include because Christians must worship God a certain way, such as a formal Liturgy. The closest he gets is saying "corporate" worship provides a "unique joy" that private worship does not. This is precisely why the whole idea of denominations are disappearing and collapsing into to go-it-alone 'house churches'.
This leads me to the second article, "In Praise of Denominations," in which a popular Reformed blogger is trying to validate the idea that bitter doctrinal divisions within Christianity is a good thing! (1 Cor. 1:10-11) For example, he says Denominations are critical because they provide members with "theological precision," the ability to have Church discipline, intervene in controversy, and provide unity. The irony of his arguments in favor of Denominationalism is that these qualities he seeks to "safeguard" are the very things Denominationalism undermines! He doesn't realize that if a Protestant doesn't like what they see in a denomination, they can move on to one that will preach what they want to hear. (2 Timothy 4:3) He doesn't realize that only the Catholic system can truly safeguard these things. It's also important to note that none of the things he sought to "safeguard" included worshiping God a specific way, which one would think should be the most important thing to safeguard. But we can easily see why, and that's because he unwittingly holds that one denomination can be just as good as another, which ultimately means formal worship is a non-essential.
The Church explains that even common sense shows us that it's absurd to suggest one can and should worship God as they please, as if one form of worship was as good as another. And realizing that God should be worshiped in certain ways compels us to seek out that Worship which is in fact the True one. This obviously requires one to find the True Church, which is impossible if Denominationalism is the norm. This practically makes the case for Catholicism in itself!
One of the best documents the Church has issued in recent years is Dominus Iesus, in which the Church explained that while Protestants are Christians in virtue of having valid Baptism, it is wrong and offensive to speak of Protestant "churches" in any objective or formal sense. Rather, the more accurate term Rome says to use is "communities," and this is because Protestants lack Holy Orders, which is what defines the visible parameters of the Church. Included in this important fact is that Holy Orders are required for a valid Eucharist, which in turn means the Holy Sacrifice of the Mass is the formal worship God instituted and how God desires to be worshiped. Thus, to lack the Priesthood makes it impossible to truly worship God. And thus, in a very real (though not all extensive) sense, Protestants do not worship God.
