Christians believe there is one God, who created the Universe, and that in this one God there are three persons, known as the Holy Trinity; God the Father, his Son (Jesus Christ) and the Holy Spirit. Those who believe become Christians by being baptized – that is, they receive the Holy Spirit and become children of God. Jesus entered history by taking on human flesh and being born of a virgin, Mary. He was fully human but retained his divine nature. Jesus taught, ‘Love the Lord your God with all your heart, with all your soul and with all your mind’. This is the greatest and most important commandment. The second commandment is like it: ‘Love your neighbor as you love yourself’. He taught the truth in love and lived it out and was crucified for it. He took on himself all the sin of the world, and died and rose from the dead and ascended into heaven that we might all be saved. He came to teach us how to love that we might live in love with him in heaven. Christian remember Jesus’ last supper with his disciples, on the eve of his crucifixion, by celebrating the Eucharist, in which prayers are said and bread and wine are consecrated and changed into the body, blood, soul and divinity of Jesus (While retaining the properties of bread and wine) and distributed to those present.
