Samuel S. Martin has written an excellent resource for Christians seeking a soundly biblical basis for parenting without corporal discipline. The free e-book is available here, thanks to Samuel's generosity. Please consider donating to Samuel's on-going work which is ministering grace and mercy to many families. (He has no idea about that last bit :) )

That above link takes you to Why Not Train a Child, a clearing house of information and Christian arguments against the teaching of the Pearls. Great place to find gentle, sane alternatives to bringing up children.
