He doesn't have to prepare lessons or compete with the teachers. He just has to be there on the spot, often. It's surprising what results. Conversations, admittedly guarded at first, can quickly become meetings of friends. Barriers can be broken.

On most school mornings the pastor can meet and speak with more parents than he would be able to greet after a parish Mass. Inactive Catholics abound in our schools. We began this just a year ago but already there have been excellent responses. The ceremony invariably reaches families with limited parish connections and can be a stepping stone to further involvement. Non-Preference pupils are also included in blessing and to date, when this has happened parents have shown great appreciation. I see this simple and easy to organise service being another wonderful evangelization opportunity.
