A word to Lutheran pastors who, like myself, have become convinced that the traditional Lutheran (and universally Christian down to 1930) teaching against contraception is correct: Don't expect super fantastic results when you start preaching and teaching this and don't be discouraged when you don't get them.
The Roman Catholic bishops of the United States are meeting this week in Baltimore. To their credit, the Roman Church has stood steadfast in the traditional Christian teaching regarding contraception (the teaching Luther, Chemnitz, and the Missouri Synod down to the mid-20th century shared with them). As this story details, according to the bishops' own survey, only four percent of American Roman Catholics are living out this teaching.
Four percent! Only one in every twenty-five people who have heard this teaching their whole lives from their church have accepted it. How much "success" should we expect when our folks are probably hearing it for the first time?
So don't be discouraged. Be patient. As opportunity arises teach on the topic slowly. But don't be put off by a slow "conversion rate."
