I want to recommend a wonderful resource being made available by Immanuel Presbyterian Church, an Old School Presbyterian congregation in Norfolk, VA. Immanuel is making the entire Westminster Shorter Catechism available for download in high quality MP3 format. While this is not the first time the WSC has been recorded, this is the most professional version of it I have heard to date. This is a wonderful resource to make available to the members of your congregation, particularly so they can practice the catechism as they drive to and from work.
Also available for download on Immanuel’s “resources” page, are Pastor Bill Harrell’s “Minister’s Letters” in PDF format. I have been reading these for several years now and have often used them as meditations for prayer meetings, etc. I would commend them to you, especially as they give us a “pattern of sound words” that will go a long way in teaching young pastors how to write to their congregations.
BTW – Speaking of the Westminster Shorter Catechism, if you are ever looking for resources exegeting and explaining any of its questions and answers, do take a look at the Westminster Shorter Catechism Project of the Bible Presbyterian Church.
