The analysis for this chapter is based on the qualitative empirical surveys conducted in Lithuania that include the approximately 70 life histories of different age groups of Catholics and non-believers collected from 1997 to 2000 and in 2013. The social and religious experiences of the pre-war, Soviet and post-Soviet periods form the basis on which several Lithuanian generations and different types of religious identity were distinguished. Individuals were influenced first and foremost by family religious experiences, then further social choices that formed different types of life courses and social attitudes in different generations.
