Lectors read the appointed passages from the Old and New Testaments at Sunday services. They receive special training in proclaiming the Word to the gathered community.
Intercessors lead the Prayers of the People during Sunday services, calling us to remember the needs of the world for our journey through the coming week.
Oblators carry the Eucharistic elements, the gifts of bread and wine, to the Table where they are blessed and returned in communion as the transformed body and blood of Christ.
Here is a link to the customary for Lectors and Intercessors.
