[Sorry if this is a little too long.]
Why did you choose to be Lutheran?
I was raised a Baptist and all my family are still in that church. Over the last 20 years or so I had begun to question and have doubts about some points of Baptist theology. At times it seemed as though they were using elaborate work-arounds to try to make the bible fit their theology instead of making their theology fit the bible. Sometimes I thought that it was as if they were consciously trying to make the bible mean something different than what it plainly says even when it says the same thing in several different places.
(You can see good examples of this on sites like GotQuestions.org where they try to answer questions like "does the bible really say..." or "does the bible really mean ...")
The most egregious example in my opinion is the Baptist position on the 'age of accountability'. I grew to realize that it had absolutely no viable scriptural support, just vague notions, yet it formed a foundational part of their theology. I started to think that the only reason they held that position was because they needed it to fill a big hole in their theological construction. The trouble was, I didn't have anything to replace it with without tearing down a whole lot of other things in the process - 'believer's baptism', 'once saved always saved', etc. And yet that theology is what I had always been taught was correct by godly people.
In 2008 we decided to give homeschooling a try. It wasn't so much that we disliked the public schools in our town, but we wanted our three school-age children to study the bible and Christian history and we knew they couldn't get that there. It was difficult for my wife (we have two younger children as well) but the kids absolutely loved it.
A month into the school year my mother had a severe stroke that left her unable to walk or speak, and we feared at first that she would die. My mother had always been healthy and active, the heart of the family. It was very difficult for all of us, but it was the last straw for my wife and we knew something had to change. There is an LCMS elementary school in our town, and they were more than willing to accept our kids mid-term and even helped us with the tuition.
We thought that since the kids would be exposed to Lutheran theology at school we should probably check them out if only to be able to correct their possibly unscriptural theology at home. We made plans to visit the LCMS church and I started to read up on Lutheran theology.
When we walked into the church, it seemed to be very formal and ceremonial. The young associate pastor wore what looked like a white monk's robe, and the senior pastor wore a robe with a sort of white poncho over the top (it's called an alb). It was what I used to refer to as a 'piano and organ' church - no praise band or drum sets. What was really strange was that the choir and musicians were behind the congregation, up in a loft in the back. There were two pulpits (one is actually a lectern) that were on the sides instead of in the middle, and there was an elaborate altar in the very front under a beautiful stained-glass window of Christ kneeling in prayer. In the center of the altar is a large gold cross with Christ in the center (a Christ-triumphant crucifix). The people were friendly, and a good mix of professional and working class folks, all ages well represented.
When the service started it was immediately apparent that this was not our normal "youth group for adults". In my childhood I had visited the small Methodist church in my home town and recognized the style of worship through written prayers and responsive readings. The style here was similar but even more so, and I recognized many of the passages as being straight from the bible.
One concern for us had been that they might be theologically and culturally Liberal. We had heard that some Lutherans were very liberal indeed. The first Sunday we visited, however, happened to include a time of recognition and support for Lutherans for Life, a pro-life organization, and our fears were allayed. The value they obviously placed on scripture, the challenging yet comforting sermon, and the attitude of respect and reverence before God was incredibly refreshing to see after years in the pop-culture Evangelical churches we had been attending.
About half-way into the service my wife and I looked at each other and both whispered "This is really great!" with big smiles, surprisingly. We really liked what we had found and kept coming back for more. When the pastor announced the beginning of a new Adult Inquirer's class, we knew we wanted to go even though it was a serious commitment of time - every Sunday evening for 16 weeks. In this class we were taught the history of the church, how Lutheranism began, the basics of their doctrines and theology, how it was developed from scripture, and how it plays out in our everyday lives.
One thing that struck me is that Lutheran theology doesn't try to fit scripture into its own framework, but simply takes the bible at its word, thereby taking God at his word even if it doesn't always make sense to us. Lutheran theology is not afraid to say about certain things "We stop trying to explain this here because that's where the bible stops teaching." Lutherans are not afraid of mystery and paradox, simply because in scripture we plainly see mystery and paradox displayed. They let reason inform scripture, but do not attempt to let reason rule over scripture.
When the class was finished we were asked to prayerfully consider joining the church. We met with the pastors on several occasions for very open and honest conversations. Then, on May 9th, 2009, my wife and I were confirmed.
On that same Sunday this former life-long Baptist was overjoyed to see God place his Name on four of our five children through the waters of Holy Baptism. (Our oldest had already been baptized in the name of the Triune God in a Baptist church, which is also accepted as valid.) On Ascension Day (May 21st) my wife and I received for the first time the true body and blood of our Lord given and shed for us for the forgiveness of our sins through Holy Communion.
I firmly believe that we have found the most scriptural expression and most orthodox form of Christianity. After having learned how to rightly divide the word as God's Law and God's Gospel, how the entirety of scripture centered upon Christ, after having learned to view my life, others, and the world through the lens of the Cross of Christ, and after having experienced Almighty God coming to me personally through the sacraments he himself established, I know that I could never go back to the Baptist theology I was raised in.
One aspect of Lutheran Christianity that I especially appreciate is how the Theology of the Cross has helped me to cope with the suffering my mother has undergone and the state of reduced ability that she is now in. Getting my focus off trying to live the 'victorious Christian life' mostly under my own strength and refocusing my attention on Christ and how he is intimately familiar with the suffering we experience in this world has helped me immensely. Jesus said, "In this world you will have troubles, but take heart, I have overcome the world." (Jn 16:33b)
