I wouldn't travel far to go to an ETS meeting, but if it's in your area, it would be worth the visit.
I want to add a disclaimer to that statement. It would be worth a visit if you are a mature church member with accountability to your church and pastor. Great harm could come from being enamored with evangelicalism. It holds a potential very dangerous allure for some because of the intellectualism. I wouldn't want just anyone to go. Don't take what I wrote as a recommendation to you. So, I am backtracking a bit after some thought about it. Only Thomas Ross, fellow contributor here, questioned me about this, so it isn't a reaction to some big opposition.
What I liked about it, and what others might, was hearing and reading biblical studies from people who are well-equipped with the technical skills and knowledge for exegesis. They have put some time into certain issues, studied them out, and made presentations. However, there are also wrong views presented and some horrible doctrine and practice. I don't believe the ETS represents New Testament Christianity because of its members' several wrong beliefs and bad practices, including a lack of biblical separation.
Thinking through a decision to attend an ETS meeting can be an edifying exercise. I don't think someone should receive theological or biblical instruction from someone who does not teach the same doctrine as his church. It is why I don't believe in sending a young person to a Bible college with teaching that differs from his church. It is one thing to learn math or computer science or English grammar at a secular school, and it is quite another to learn doctrine at a school that contradicts the doctrine and practice of your church.
Paul commanded Timothy to "charge some that they teach no other doctrine" (1 Tim 1:3) and in the next verse not even to "give heed" to it. In 1 Timothy 6:3-5, "If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness. . . . from such withdraw thyself." That scriptural admonition should give someone pause about attending ETS.
Some may wonder about buying books from these men and reading them, in light of this teaching from God's Word. How would using their books differ from attending the meeting and hearing them in their sessions? I believe there is a difference with books. We don't have to take heed to their teaching when we read their books, I don't believe. Neither do we need to withdraw ourselves with a mere book.
So does attending the sessions of the ETS violate the teaching of 1 Timothy? "Withdraw thyself," I believe, speaks of "the breaking of fellowship, no longer to be in fellowship." We are not to fellowship with these and attending, I think, does not mean fellowship (cf. 2 Corinthians 6:14). "Give heed" is present tense. We are not to keep giving heed as a practice. I don't think occasional attendance to these meetings constitutes a practice. I am open to input on this one.
Most readers know here that I don't subscribe to evangelicalism and am a constant and severe critic. However, that doesn't mean that someone such as myself cannot be influenced by evangelicals. I believe that one of the major reasons for the rampant and widespread erosion of fundamentalism has come from the influence of evangelicalism upon fundamentalism. Fundamentalists have allowed far too much evangelical influence. They have sought it out. Many fundamentalist institutions promote evangelicals more than they do fundamentalists, especially in their book stores, and without much disclaimer. Fundamentalist seminaries often elevate the ETS with little criticism.
We need to be careful with evangelicalism. It can touch in the ways that are most alluring and damaging. In evangelicalism, we can see significance, career, promotion, and accolade. For these reasons, I warn my readers about the ETS. Folks, they might seem intellectual, but they aren't "smart" enough to "get" separation, and that's all over the Bible. So watch out!
