Jesus did and said many things during His life to show people how much God loved them. The seven most important things Jesus did to show us how much God loves us was to give us the Seven Sacraments. These were actions Jesus started and wanted us to continue so His message of love could be continued in every age.
The Sacrament that we receive most often is the Sacrament of the Eucharist: Holy Communion. It is the Body, Blood, Soul and Divinity of Christ.
At the Last Supper, Jesus took bread, broke it, gave thanks, and said,
"Take this and eat; this is My Body."
He then gave it to His discipline. He also took a cup of wine and said,
"This is the cup of My Blood in the new covenant poured out for the forgiveness of sins. Do this in memory of Me."
When Mass is celebrated, we do what Jesus commanded us to do. Jesus is truly present in our midst.
Saint Paul also reminded us that we are not only one with Jesus; we are also one with our brothers and sisters. We should treat them with as much respect as we would show Jesus.
We are even called to go forth from church after Mass and share the Good News of how much God loves us with everyone whom we meet.
