Rev. Danny Hyde's excellent "welcome" guide for those new to Reformed and Presbyterian churches is available as a free eBook download. Here: Welcome to a Reformed Church--Ligonier, or here: Welcome to a Reformed Church --Amazon
Rev. Hyde's very helpful and informative book is required reading for new members classes at Christ Reformed Church, and I highly recommend it.
