First, do you have a membership class targetted to adults coming into your church as new believers, from other CRC's, and/or denominations?
Second, what materials do you use for that (self-made, denominational resource, video, etc.)?
I've been using Louis Tamminga's booklet Church Membership and You. But it has recently gone out of print. I know it's been made available in PDF format, but it's inconvenient and expensive to print/copy/assemble. Still, I like the organization of the booklet, and the brevity with which it covers the topics.
My practice is to invite everyone wanting to explore membership to take the class (even transfers from other CRC's). The class will meet for 3 or 4 sessions and cover the contents of that little book, with follow up to happen ad hoc.
So what do you do with new members, both those who transfer from other CRC's and those that come in as new believers or from other denominations?
