I remember my mom asking me once during a strong Piper phase I went through if I disagreed with John Piper on anything. Even back then I didn't agree with Piper on all points theological. Today, that disagreements are more numerous. For example, he recently posted an article "Why Women Shouldn't Run for Vice President, But Wise People May Still Vote for Her". Wow.
In actuality, I can't think of anyone I'm lockstep with - not Calvin, not Edwards. I'm a nomad theologically. I don't fit in any denomination that I know of, except maybe the EPC. Makes it hard to find a job (!), but thankfully I'm not looking. I think there is a wisdom in not being overly worried with consistency (it is the hobgoblin of little minds), and being humble in our approach even to our own beliefs. I honestly disagree with things I believed even a year or two ago. I learn, I grow, I rethink, and I think it's good. I love being at a place like ECC where I'm constantly exposed to people who disagree and with a staff who is open to thinking and rethinking things.
