Also note that what you see on the Puritanboard is basically the strictest form of Presbyterianism you'll find today, and they even have strong arguments amongst themselves. Many conservative and evangelical Presbyterian churches have "praise teams," Christmas trees, etc. and for all practical purposes follow the normative principle. For example, there's a big fight in the PCA now over intinction, which is dipping the bread into the cup instead of taking the elements of the Lord's Supper separately they way that appears to be seen in Scripture. If someone is looking for the kind of church that is advocated on the PB and happens to drop into a random PCA church, he is likely to be disappointed. The OPC will be more like what is described in the first post with old hymns. And it won't be "In the Garden" or Stamps-Baxter gospel songs either, which is what comes to mind when many Baptists think of "old-time hymns." IMO a lot of the lyrics in those kinds of songs are no better than the shallow repetitive "7-11" or "Jesus is my boyfriend" praise choruses that many of us deride.
I was a member of a PCA church for 25 years. And yes, I believe you to be correct that they are not the strictest of Presbyterians. They are more conservative that the PCUSA. There are some reformed type Presbyterian churches that are very strict as far as rules. My sister goes to one in Michigan. Once when we were there, they would not let me take communion because I am a Southern Baptist, in particular a deacon. Yet my Dad, who was sitting by me, was allowed to take it because he was a PCA elder. It was no big deal to me.
I do appreciate the beliefs that Presbyterians and Baptists have in common, such as eternal security. To a degree, there is agreement on Doctrines of Grace. This issue is now a big debate within the Baptist faith as can be seen by the constant ad nauseum threads on this board. I also take away from the Presbyterian church with me the idea of open communion, which each local autonomous church differs on.
However, that is where the similarity ends. The biggest deal to me is baptism. Nothing could be clearer to me in two respects. One is the mode, as this is how the Lord was baptised. The other idea is the baptism of infants. They claim it is not a baptism after salvation, as the Bible clearly commands, but a vague concept of a convenant relationship between parent and child found in the OT. One might as well baptise their pet cat, as the cat and the infant understand the Gospel equally well.
Someone made fun of the "howdy time" and the church invitation within the Baptist faith. While no specific Biblical reference as an example, neither is there is prohibition. PCA churches, and reformed especially, the order of worship is so stoic, regimented, and cold that it reminds one of a library more the a house of God. Fellowship is a part of the Christian life, and is meant to unify a congregation. Praise the Lord there are not a bunch of self centered presbyters dictating how a local church conducts its service. As far as the end of the service, the invitation which does not exist in the Presbyterian church, despite its shortcomings beats the fire out of the Presbyterian mode. It goes something like this.
1. End of a boring sermon preached above the interest or understanding of the congregation and most are already asleep
2. Have a short choral response and pray
3. Time to leave, everyone march out like nice little quiet robots
No thanks. I will take the invitation anytime as a means for someone to express a need in their lives or the Spirit working in their lives.
Then we have the unBiblical practice of how to accept members. In the Presbyterian church, there is something usually like a six week communicant's class, where questions and answers are memorized. Then a group of men called elders decide whether or not you can become a member. (more later on elders) Then, to become a member, if a youth, one is paraded out before the congregation to mimic back the question and answers they learned, then the congregation like good little soldiers, ratify the elders decision. That is not what I call a Spirit lead road to salvation, or the Biblical way to receive members. In Acts, the new members were received the same day after they believed. Goodness gracious, how on earth did they ever manage to join without a presbytery. God does the saving, God gives the faith, not a board of elders and their stoic mindset.
Then there is the creeds and confessions. Every Sunday we said the Apostles Creed and sang the doxology. That creed, and others that are memorized, are nothing more than time fillers for Sunday morning worship. They are either chanted or parroted, and are mindlessly repeated Sunday after Sunday. A parrot can do that. They are man made documents subject to flawed theology. For example, in the Apostles Creed, it states, "I believe in the holy catholic church." That refers to the universal church, which never accomplished a thing for the Lord here on earth. The universal church never sent out a missionary, visited the sick, prayed, administered either of the ordinances, took up an offering, praised and worhipped the Lord, or told someone about Jesus. Also, the creed says "I believe in the communion of saints." How does one believe in the communion of saints? It is not a belief. It is a fact. Chrisitans want to be around Christians. As far as the other parts of the Creed, such as "I believe in God the Father, Maker of Heaven and Earth, and in Jesus Christ His Only Son our Lord........." reading Genesis and John 1 would surrfice quite well. Creeds and confessions are a waste of time, subject to flaws, and the words are not paid attention to.
The reformed/Presbyterian church view of the church in general is incorrect. Catholics view the church as a visible universal church, while the Presbyterians view it as invisible universal. Both are wrong. The church is a visible, local church.
Then we have elder rule and hierarchies. Hierarchies are not Biblical. The NT churches are local autonomous churches. Hierarchies are a left over tradition of the RCC. Why one earth would anyone mimic an organization that one broke away from and is a cult? No presbytery is going to tell a church I serve in what pastor to call, how our budget is to be administered, what we can or cannot do with our building, or any other aspect of the life of the local church. Salaries paid to people in upper levels of hierarchy above the local church accomplish nothing, and again, it is money that might have been used to support more missionaries. At the local church level, it there is such a thing in this mindset, the church is ruled by elders. That in a Spirit filled church might not be a bad idea, but elders seem to be elected on the basis of social status instead of spiritual maturity. Over the years, I have seen very little difference in the spiritual maturity between the average elder and the average church member. Congregational rule puts in a check and balance against presbytery and elder meddleing in the work of the Lord.
Baptists did not originate with the RCC. Those groups who did seem unable or unwilling to completely seperate themselves from the organization.
