Purpose: Set in a Mexican-American community of a US Gulf Coast state, the purpose of this paper was to describe how three young siblings and their family members constructed their spiritual, ethnic and communicative identities within the context of a virtual family literacy program during COVID-19. Design/methodology/approach: This project was approached as an illustrative case study that focused on one family's engagement with a children's book in which the protagonists retell the legend of the Catholic patroness of the Americas, Our Lady of Guadalupe. Findings: The case study illustrates how the children's spiritual/religious identities were inseparably intertwined with their home literacy practices and their identities as communicators with others. The children's everyday spiritual/religious practices, routines and activities motivated familial conversations and dialogue that engage and support children's literacy development. Originality/value: Although there is a large corpus of scholarship about secular early literacy program for families with preschool children, there are few that describe the recognition and inclusion of families' spiritual/religious identities.
