A new book has just been completed: Perspectives on Tithing. It looks at the arguments for and against the continuation of the tithe for Christians from 4 different angles. I'm the editor and a contributor. Also writing chapters were Reggie Kidd (Reformed Theological Seminary-Orlando), Ken Hemphill and Bobby Ecklund, and Gary North. I was very pleased with some of the chapters and responses.
Some have asked: how can you have "four views" ... isn't it just "yes you have to tithe" or "no you don't"? Far from it! All the chapters come to slightly different conclusions and get there using very different texts, methodology, and terminology. Some might accuse one chapter of legalism and another of antinomianism. It should be released around May, 2011.
