Lutherns big thing is saved by grace and faith, not by works.
Baptism is as an infant, with confirmation when your in your mid to late teens.
C172G: In my old church we did actually shake hands during the sharing of peace.
The service is typically very liturgical, doens't vary much from week to week, toher than the hymns homily and reading.
