The only way, it seemed, for humans to escape the persecution of the demons was to offer them things they supposedly liked, especially dainthy food and sweets. Or, a human could disguise himself as one of them and join in their roaming. In this way, they would take him for one of their own and he would not be bothered. This very custom has come down to us, practically unaltered, as our familiar Hallowe'en celebration. As it is now observed in our day and society, with gross excesses of candy and costumes that look to the occult or damned for inspiration, it has no place in a Catholic or Christian home.
Many families do what the early Christian fathers did.
When confronted with a pagan festival, the early Church found a way to 'Christianize' it, to keep the celebration but change the focus. Since feasts, celebrations, and traditions are the way every culture transmits its values to the next generation, and how a society teaches each other and its children about the faith and beliefs of that society, the fathers of the early Church used these modified pagan celebrations to teach the Christian faith and transmit its values. Basic to the idea of an All Saint's Eve party is the theme of saints. Beyond that, the possiblities are almost endless, limited only by your imagination and resources. Here are a few possibilities to consider.
