I'm Lutheran (Missouri Synod Australia - more conservative than US Lutheranism, from what I've heard).
I follow Christ and his teachings as laid out in the Bible
Some of our beliefs include:
A Triune God - Father, Son, Spirit. One God in three persons. Not three gods
The Bible - God-breathed by the Holy Spirit
Salvation by faith alone
Jesus - fully God/fully man (when he was born, lived, died, ascended and is now)
Traditionally baptised as babies but can be baptised at any time
