Reading the article on Baptism and salvation I found an interesting quote: "The Corinthians conceived of baptism as a sacrament which united them to Christ and thus gave them protection from all spiritual powers, unlimited authority and a confident hope of final resurrection. This erroneous view may have led some of them to be baptized on behalf of their dead, unbelieving relatives." M. O. Fape, “Baptism,” in New Dictionary of Biblical Theology, ed. T. Desmond Alexander and Brian S. Rosner, electronic ed. (Downers Grove, IL: InterVarsity Press, 2000), 396. It just happens that the Church Catholic has shared the sacramental view of baptism for its entire history. It was only with the rise of the radical reformers/restorationists, beginning with the Anabaptists, that this understanding of baptism was challenged. The "erroneous view," in this case, lies not with the Corinthian Christians, but with the Anabaptist sympathizer who wrote this article. The Lutheran perspective on this is found in Augsburg Confession Article V: [V. Concerning the Office of Preaching]  To obtain such faith God instituted the office of preaching, giving the gospel and the sacraments.  Through these, as through means, he gives the Holy Spirit who produces faith, where and when he wills, in those who hear the gospel.  It teaches that we have a gracious God, not through our merit but through Christ’s merit, when we so believe.  Condemned are the Anabaptists and others who teach that we obtain the Holy Spirit without the external word of the gospel through our own preparation, thoughts, and works. Robert Kolb, Timothy J. Wengert, and Charles P. Arand, The Book of Concord: The Confessions of the Evangelical Lutheran Church (Minneapolis, MN: Fortress Press, 2000), 40. I suspect that this book, like many, suffers from the lack of a Confessional Evangelical perspective. It is a common short-sighted error that thinks only in terms of Calvin and Arminius, forgetting the one who preceded them both, Dr. Martin Luther.
