It must be very difficult to find an acceptance amongst Calvinists if you're very liberal surely.
Anyway, can you give an example of where a fundamentalist approach would yield a different exposition than a reformed one.?
What about creation/6-days/end-times/Israel etc?
As far as I can tell, not all fundamentalists are Calvinists, nor are all Calvinists fundamentalists. Describing Calvinism isn't easy, because Calvin said lots of things, and different groups emphasize different ones. A lot of people think of the 5 points. But predestination was not such a high priority with Calvin that I think he would want to be known primarily for it. Most of what he taught was held in common with other reformers. But one specific approach (which I think is shared with Lutherans) is the relationship between Scripture and tradition. Protestants correctly emphasize the importance of Scripture. But for the magisterial Reformers, Scripture is not interpreted by isolated individuals. It is the Church that interprets it. But the Church must always been willing to listen to individuals that believe it has gotten off track and needs to be corrected by Scripture. This view often doesn't appear on peoples' lists of Reformed distinctives because I'm not sure it's specifically argued by anyone. It's just the way the tradition actually works.
Similarly, the approach to leadership is distinctive. Reformed churches are known for developing leadership among its members. The focus of the church is not the pastor, but the Session. The Session is elected, but elders are also ordained. This means that once elected, they are responsible to God more than to the people who elected them. Elders have been a continuing inconvenience in ecumenical discussions. Other denominations can accept our pastors, because there are equivalent offices in all traditions. But there really isn't an equivalence for Reformed elders in most other traditions.
There's also distinctive Reformed positions on the sacraments. It's actually not far from Lutheran: there are two sacraments, they are more than just memorials. In communion we actually touch Christ's body, though we think that the Holy Spirit is involved in making this happen. (During the Reformation era, the difference between our explanation and the Lutherans' was overemphasized. I think this was for institutional reasons: Lutherans and Reformed felt they had to justify their existence as distinct traditions. They they glommed onto the few subtle differences and overplayed their importance. Fortunately the PC(USA) and ELCA today are in full communion.)
Of course the thing you normally think of as Reformed are predestination and covenant theology. I do believe in predestination. I also think the covenant is key to understanding what Jesus was doing, though the specifics of, say, Westminster are post-Calvin and I don't buy all of it. (Also, Calvin only taught 4 of the 5 points, and I'm inclined to follow him.) I'm just not sure that these things are really keys to being Reformed.
This more complex vision of what it means to be Reformed isn't often found on web sites, which tend to be from conservatives and tend to focus on flashy things like predestination. But it's there. For more details see reformedtheology.org/SiteFiles/WhatIsRT.html, and the wonderful article by Garrish that they point to: reformedtheology.org/SiteFiles/GerrishArticle.html (Sorry that the links are mangled, but the system won't let me post real links.)
This vision isn't the same as fundamentalism. Fundamentalism is about defending some key doctrines against modernism. There's nothing wrong with defending the truth, but the doctrines chosen as key represent only a small part of the Reformed tradition, and in some cases I think the formulations chosen was too narrow. E.g. Calvin and the Reformed tradition in general never took as narrow a view of what it means for Scripture to be true as the fundamentalists.
Please remember that fundamentalists are vocal, but in the minority in the Reformed churches in the US. The original Reformed Churches in the US were the PC(USA), RCA, and United Church of Christ. The fundamentalist Reformed bodies are small offshoots that believe the main bodies have rejected true Reformed faith. I don't know the UCC as well as I should, so I don't know how much they still emphasize the Reformed tradition. They are known as the liberal end of the tradition, and may be to the left even of me. The PC(USA) maintains a distinctive Reformed flavor, and I believe the RCA does as well. However my preference is to emphasize what is in common among the original Reformers, and thus look at a Reformation tradition that includes the Lutherans, and takes advantage of their good ideas as well as Calvin's.
