This article examines the relationship between children and the Eucharist at Trent by studying the Acta of Sessions XIII and XXI and by historically and theologically contextualizing Session XXI. It argues that Trent’s teachings on children and the Eucharist are motivated more by concerns about what is necessary for salvation than by reflection on children’s spiritual growth or membership in the church. While the council adequately articulates the requirements for salvation, it does not offer a comprehensive eucharistic theology, which could lead to deeper reflection on children’s relationship with the Eucharist.
