When you ask a Catholic about any Mass, you will get different answers, not because of what we bring but what God is giving to us, that day, at that time. Sometimes, I don’t realize what that is until days or weeks or even months later. There is no expectation that everyone experiences exactly the same thing in exactly the same manner.
What is worship? There is internal worship and external worship. Catholicism has both.
Contemplating, meditating, studying and prayer are the internals of Catholic worship.
The externals are the Sacraments. Baptism first. Confirmation. Eucharist, which has no comparison in Mormonism and many other religions. All Catholics ask of the Church these three things. Reconciliation, Marriage, Holy Orders, Anointing of the sick…all Sacraments where God is worshiped.
Other external and internal forms are works of mercy. Feeding the hungry, praying for the dead, etc.
At some Masses, the clergy lie prostrate on the floor before God. At all Masses, we stand when we pray and we kneel at His Sacrifice. Why? Because we believe that God is Present, and when God is Present, you better believe we’re on our knees. Worshiping Him.
Catholics worship God in a community of believers, in many ways, innumerable really. Religious orders, religious education, retreats, liturgy of the hours, lauds, vespers, etc. etc.
When any of us celebrate Mass, we do so with the whole Church. All of us and the angels, prophets, Apostles and Saints. This communion of the whole Church, worshiping together, I never found present in Mormonism.
The other thing different about Catholicism, is the liturgical calendar. Every year, for hundreds of years, the cycle of Jesus’ birth, life and Resurrection is relived. We start with Advent, awaiting the time of His birth, we just celebrated the Christmas season, all 12 days, which concluded with celebrating the Baptism of The Lord.
There is no such thing in Mormonism. Christmas is one day, there is no anticipation to His birth, waiting, for God to come into the world. Of course, we know very well that God is in the world, now, but we celebrate that time like it is occurring anew. Every year!
There is no Triduum, where the world is in mourning, the still days, the dark days, where we remember three days where He was believed to be dead, and gone from those He loved. And the joyous celebration where we sing alleluia together, in praise of God and His Mercy, our Salvation.
We worship every aspect of Jesus, because in every aspect we believe Jesus is God’s Revelation of Himself to the world. We believe the whole of Jesus’ life is to be celebrated, which is itself a form of worship, all year long, every day, every year, as we wait for and anticipate His return.
