The entire tenet of the Roman Catholic faith IS the concept of the salvation of the people by the crucifixion of Jesus on the cross. His dying on the cross is what, according to Catholic belief, opened the doors of Heaven.
It is taking some time out your life to worship God. When we receive Holy Communion, we are partaking in a reenactment of Jesus' Last Supper and death. We are partaking in Jesus' death to be risen with him.
The life, death, and resurrection of Jesus Christ.
Because Jesus Christ, whom we Catholics worship as God, was crucified on a Friday. This is memorized every year especially on Good Friday, the Friday before Easter Sunday (which is the feast of Christ's resurrection after His death).
Jesus (if he existed) was Jewish, so he practised Jewish worship. Christianity didn't exist until after his death, it was invented by the Holy Roman Empire, not Jesus himself.
It is a symbol of his death.
Catholics celebrate Easter in celebration of the day Jesus rose from the dead after dying the previous Friday (Good Friday). The event marks the point at which all the prophecies about the Messiah are fulfilled, thus beginning the Catholic Church
It is a Palm Sunday as it called by now by the Catholics.
Catholics are Christians and as such, believe in Jesus Christ, His Crucifixion, Death, Resurrection and Ascension, promising to come again.
On Earth? Worship. After death? Heaven.
Christians do not require any "equipment" when praying. However, some Catholic Christians use the rosary. Both Catholic and Orthodox Christians are more likely than Protestants to use visual representations of Jesus and the saints in their worship, although Protestants often have an (empty) cross in their places of worship as a symbol of Jesus' death and resurrection.
The cross symbol can traced back 2000 years pre-Christ and used by non-Christian cultures as a "magic" to give protection or good fortune. Many Bible Scholars have agreed that Jesus was put to death on an upright stake not two pieces of timber placed at any angle. True Christians wholeheartedly believe that Jesus death provides us with an opportunity for deliverance; however, having a symbol of the tool used to end his life here on earth can lead to it becoming an object of devotion or worship, which is idolatry. As a result, true Christians refrain from using the cross in their worship.
Either a cross, signifying Jesus' death and resurrection, or a fish symbol, representing a miricle Jesus performed
