Corpus mysticum underwent a complex theological
evolution. Originally, in the ninth century, corpus mysticum referred to the consecrated Eucharist — the body of Christ present in
the sacrament — while corpus verum (the true body) referred to the historical body of Christ. Over time, through a process described by the historian Ernst Kantorowicz in
The King's Two Bodies, the terms shifted: corpus mysticum came to refer to the Church as a social body, and corpus verum to the Eucharist. Students should note that this terminological history is relevant to any poetry that draws on body
imagery in a theological or political context: the body politic, the body of the Church, and the sacramental body are all related through this tradition. Related terms include the body politic, communitas (the community of belonging), and the Pauline
image of the body with many members.
