"Transubstantiation" Natural Recordings by Native Speakers
Transubstantiation is a doctrine in Roman Catholic theology that holds that in the Eucharist, the bread and wine used in the sacrament are transformed, or transubstantiated, into the actual body and blood of Christ, although they retain their outward appearances and properties. This means that the bread and wine are still bread and wine, but they have been spiritually changed into the real presence of Christ.
The doctrine of transubstantiation was first formulated in the 11th century and was declared a dogma of the Catholic Church at the Fourth Lateran Council in 1215. It is based on the teachings of St. Thomas Aquinas, who argued that Christ is present in the Eucharist under the species of bread and wine, but that the accidents of the bread and wine remain.
Transubstantiation is distinct from consubstantiation, which is a doctrine held by some Protestant denominations that holds that Christ is present alongside the bread and wine, rather than being transformed into them.
Transsternal means "across the sternum". However, "transtubercular" is not a commonly used word in the English language.
