4th Sunday of Lent

The words 'Passover' and 'Paschal' are often heard in the prayers of Mass...but what on earth do they mean? As we approach Holy Week, and Holy Thursday - when Jesus celebrated the Last Supper, which was His celebration of the Jewish Passover meal with his Jewish disciples and became the outline for the Eucharist that we celebrate each weekend as Catholics - I think it very appropriate to revisit the meaning of those words 'Passover' and 'Paschal' and the rich tradition that they draw us into, even unknowingly, at every single Mass!
