Two years before CPH published Planned Parenthood and the Christian, by Concordia Seminary theologian Alfred M. Rehwinkel, CPH published Walter Reiss's Teenager, Christ Is for You (1957). After promoting abstinence until marriage, Reiss concludes (p. 44):
And when you do marry, you'll find out that sex means a lot more than just fun or excitement. Sex is all wrapped up with God's way of creating people -- more temples for His presence [1 Corinthians 5:19]. When you take your first look at your first baby, someday -- whether you're a young man or a young lady -- you'll be mighty glad you handled sex with respect and used it with love.
