During each catholic mass, a micracle happens. It is called the Miracle of Transubstantiation
As define by the Council of Trent after deliberations from December 13, 1545 to December 4, 1563, at every Consecration at Mass, the bread and wine changes into the literal body and blood of Jesus Christ, while the appearance of bread and wine remain. It is a miracle present at every Mass.
This teaching distinguishes Catholicism from Protestant views that define the bread and wine as symbolic or not fully embodying the literal body and blood of Jesus.
