Reference groups and significant others are vitally important in both the f
ormation and the persistence or change of normative as well as deviant beha
vior patterns. Thus one's initial religious beliefs and behavior (or lack t
hereof) reflect the socializing influence of the family. However, the situa
tion may change when young people leave home for education or work, as demo
nstrated by research that shows decreases in religious beliefs or church at
tendance when young people leave home to attend college. In contrast to the
pattern whereby religiosity declines in a college or university environmen
t, we maintain that students who develop close ties with others who are rel
igious, especially in a highly religious community, will maintain the same
patterns of high commitment developed in their families. Specifically, we h
ypothesize that religious beliefs and participation will be positively rela
ted to (1) parents' religious beliefs and practices and (2) current friends
' religious beliefs and participation. These hypotheses were tested with a
sample of college students living on campus (n = 339). The data support the
argument that students' current religious beliefs and behavior are related
to both their parents' religiosity and the reinforcing effects of the reli
giosity of their current friends.
