Immerse Yourself in the Large Catechism
I cannot commend Luther's Small and Large Catechisms to you strongly enough, and someday I hope to finish recording comments on the Large Catechism and updating the Catechism Lockdown blog, but for various reasons, that won't be happening anytime soon.However, you can read the Large Catechism (and the entire Book of Concord) online here
You can listen to an audio recording of the Large Catechism here (The Librivox app is also downloadable for iOS or Android: I highly recommend it)
