Elder rule is a disaster. I grew up in a PCA church, and was a member through my young adult years before becoming a Baptist for 35 years now. First of all, elders are elected usually based on social status, not spiritual maturity. Elder rule also implies a hierarchy, which means the congregation has little say in issues with the building, calling a pastor, and other such issues.
First of all, there is no evidence in the NT that any of the local churches Paul visited had a hierarchy. Baptist churches are local autonomous New Testement churches. There is usually congregational rule, one elder or pastor, and deacons. If one wants elder rule, there are Presbyterian, Methodist, and Lutheran churches all over the place. If you like a hierarchy, the RCC might me the fit for you.
Elder rule has a strange way of transforming into elder worship. I agree with the poster above, that either congregational or elder can be abused, but on the whole, elder government is much more abused. I wonder how many of you all have actually served in a church with elder rule for decades.
How would you as a lay person like no say so in calling a pastor, making changes to your church building or other issues you take for granted? My guess is those in favor of elder rule never experienced it. Also, the average elder has no more knowledge of Scripture than the average church member. They usually have a higher salary.
Also, one cannot serve as an elder and deacon at the same time. The nature of the two offices is totally different.
