Religion, culture, and ethnic heritage play a significant role in shaping migrant identities. This paper investigates the interplay of these factors in the identity formation of African Christian migrants in Europe. In particular, it analyzes how second-generation (2G) migrants integrate Western secular values with Pentecostal orientations to facilitate upward social mobility. The analysis is based on a critical review of existing literature, supported by selected ethnographic case studies and qualitative interviews discussed in the cited works. By drawing on empirical research from various European contexts, this study aims to provide a rigorous and multidimensional understanding of intergenerational identity reconstruction among 2G African Christians. By centering the Pentecostal family as a primary site of socialization, this paper explores how 2G African Christians both distance themselves from indigenous African spirit cosmologies and adapt elements of these cosmologies to pursue secular, achievement-oriented objectives. This dialectical engagement highlights a generational shift: while first-generation migrants depend heavily on religion and religious institutions for integration, 2G migrants prioritize secular aspirations as they navigate socioeconomic structures, negotiate belonging, and construct new forms of transnational identity.
