The announcing of the “Good News” and the transmission of the faith to next generation is one of the most important duties of any Christian community. At St. Catherine of Siena we take this very seriously.

For Parents



The conferences for Parents of Children of First COmmunion and Confirmation have been a great experience of faith for all those who particiapted. Even thoiugh at the beginning there was a bit of resistance, by the end of the course all were happy and grateful that they had an opportunity to revisit and experience anew, the faith that probably they had received at their First Holy Communion.

This year we will continue amking even better, with a program already prepared, which is called ALPHA SENIOR.

We will be very happy to see the new group of Parents for the next School Year.


This year when you bring your children to catechism for FIRST COMMUNION or CONFIRMATION you may take advantage of a program offered by Fr. Walter for parents and adults. At the same time your children will be in the MAIN HALL, you may go to the ZANON HALL where a program will be offered on the SACRAMENTS. This will help you greatly to accompany your child through the process of learning the faith and coming to experience the real presence of God in the Christian life.
