Concomitance The state in which one object is associated
with and simultaneously present to another object. The doctrine of concomitance
is used to explain why the entire Christ—Body, Blood, and Soul and Divinity—is present
under each Eucharistic Species of bread and wine. When a validly ordained
priest, using valid matter with the proper intention, during Mass says, “This
is My Body,” the Body of Christ is substantially present, while His Blood, Soul
and Divinity become present by concomitance, precisely because His Body cannot
be separated from His Blood, Soul and Divinity. Christ cannot be divided. (“Concomitance,”

Stravinskas [rev ed.; Huntington, Ind.: Our Sunday Visitor, 1998], 262)
