From Scripture

                                 Matthew 28:16-20;
                                 Jesus gives disciples their charge

                                 When Jesus appeared to the Eleven on the mountain top in Galilee, it was so the crowd with them could witness his Resurrection and get instructions for next steps.  Now that they had been taught and witnessed Jesus' glory, he wanted them to teach others how to live as God's children.
                                 As his followers today, that's our mission, too.
                                 Jesus gave his listeners three commands :  Go, make disciples of all nations, and baptize them.  Baptism signifies a renewed relationship with the Father, as revealed through the Son, to be filled with the Holy Spirit --- in other words, the Holy Trinity.
                                 The Trinity is a mystery most of us will never understand it to believe it.  And we make the Sign of the Cross and say the words Jesus said, "in the name of the Father, and of the Son, and of the Holy Spirit."  We are also reminded that the Cross of Jesus is the only means by which we can follow Christ into the eternal life of the Trinity.
