Pavlina thinks Christianity is a way of life and it is to be lived out on a daily basis in relationship to oneself and in relationship to the community of which one is a part. To be a member of the SCM or the WSCF is to understand oneself much more deeply by listening to others, by working together and being in constant dialogue; to stand for living out the faith together for justice.
