The Catechism teaches us that we were created to know God, love God, do His work in this world, and be happy with Him forever in the next. Dean reminded all of us that each of us is a miracle. When we were conceived in the womb, we were the size of the dot you make with a very sharp pencil. She showed us all the stages of development, from zygote, to embryo, to fetus (a Latin word that means "little one") and pointed out the various things that the unborn child experiences in the womb at each stage of development.
