Damian Stayne started Night of Light around 15 years ago.
He told Premier 31st October should really be about the eve All Saints' Day.
He said: "All Saints Feast is the celebration of the success of the work of the cross.
"The devil seems to have hidden that message by disguising Halloween into something about darkness and death and witches.
"It's become a celebration of darkness and things that are very unhealthy."
Night of Light has received a stamp of approval by the Vatican and celebrations have taken place in small chapels and cathedrals in parish churches, monasteries, schools and homes in several countries.
Stayne said: "The kids who come to our Night of Light parties have got to have a better time than all their friends who are doing trick or treating.
"We invite them to come and dress up as Saints their heroes of faith, and we do some kind of teaching, a little tiny short thing, that gives them an aspiration for living in God."
To set itself apart from traditional Halloween celebrations, the event is decorated with pumpkins that have happy faces carved into them.
Night of Light also encourages people to place a light in their window along with a picture of Jesus as a sign to passers-by that it's a Christian household and Christ is "their light".
