First Holy Communion:
Opportunities for First Holy Communion are normally offered in second grade. Preparation for First Holy Communion begins when preparation for First Reconciliation is finished. This is offered to all second graders and to any older child that has not previously received the sacrament.
The Eucharist - Source and Summit of Ecclesial Life
The Eucharist is "the source and summit of the Christian life." "The other sacraments, and indeed all ecclesiastical ministries and works of the apostolate, are bound up with the Eucharist and we are oriented toward it. For in the blessed Eucharist is contained the whole spiritual good of the Church, namely Christ himself, our Pasch." (CC 1324)
