Fr. Thomas Joseph White, OP, explores the theology of transubstantiation and concomitance, discussing Aquinas' views on the relationship between bread's accidents and Christ's body, host size's impact on communion, concomitance in the Eucharist, real presence under each species, consecration's effect on elements, and the unique relationality between Eucharistic accidents and Christ's body.

Formal Presence Versus Concomitance
- Transubstantiation renders either Christ's body or blood formally present while the rest is present by concomitance.
- Aquinas distinguishes formal presence by sacramental power from natural concomitants like soul and divinity joining the rendered body or blood.
Whole Christ Present Under The Species
- The whole substance of Christ, including soul and divinity, is present in the sacrament though accidents of bread and wine remain.
- Aquinas argues the conversion terminates in Christ's body or blood while soul and Godhead are present by real union.
Holy Saturday Hypothesis Reveals Concomitance Limits
- Consecration could have different concomitant results during Holy Saturday when Christ's soul was separated from his body.
- Aquinas uses this hypothetical to show soul may be absent by concomitance if historically separated from the body.
