Fr Tim has posted about the celebration of the Blessed Virgin held in his parish school for the month of May. A must see!
For the catechists out there: notice the wide age range of participation - younger children can bring up flowers etc, older ones can read, everyone can sing. And the visuals also communicate volumes, even to "grown ups".
A non-Liturgical celebration also gives the opportunity to use considerable catechetical imagination without offending the nature of the liturgy.
I recognised in Fr Tim's post many aspects of pastoral strategy that I try to use in running Eucharistic Adoration in my own parish.
