This research explores the magnitude, sources, and consequences of differences among age strata in various dimensions of religious orientation and practice. A national sample of 4444 Lutheran church members, ages 15–65, completed a 740‐item survey. From these data six age groups were empirically formed; these exhibited significant differences on 43 of 52 major scales. Patterns of age strata differences supported a “selective gap” theory rather than a “great gap” interpretation of contrasts among age strata. The youth stratum, 19–23, was found to be most heterogeneous in their beliefs, attitudes, or life styles. Although some within‐stratum solidarity was evident, it generally was weak and overshadowed by lineage solidarity. Implications of combined aging and cohort effects conclude the discussion.
