Prayer and Worship

If you are interested in learning more about one or more of our ministries, please contact:

Tommy Sustaita, Volunteer Coordinator at 512-600-8190 or tsustaita@st-william.org to schedule a meeting.

Parishioners have many options for volunteering in our prayer and worship ministries.  The parish itself depends upon those who pray and offer sacrifices for it, and on those who enrich it through various celebrations of the liturgy and feast days throughout the year.

Saint William is fortunate in having beautiful music at our liturgies.  Many devoted volunteers offer their time and talents within the music ministry.

We are regularly recruiting more singers and instrumentalists for all our choirs. We count on the efforts of people just like you. You can contribute to the beautiful music that touches so many during the Mass. If you are interested in joining us, please email music@st-william.org for more information. 

We are very privileged to have four ensembles that serve our parish.

• Several times a year, the ministry offers an hour of Guided Adoration for children of all ages to attend with a parent or responsible adult.  Please watch the bulletin for upcoming dates.

• The Just Jesus and Me page on the website, Guided Children's Adoration, offers a List of Things Children Can Do in Adoration and a variety of downloadable prayer materials.

Adults in the community who feel the call to pray for the sick and the devotion to the Eucharistic Adoration are invited to participate in our ministry, the only requirement is to have the Ethics and Integrity in the Ministry (EIM) workshop up to date.

Joining us you have the opportunity to:

• Profess and proclaim the truth of the real presence of Jesus Christ in the Holy Eucharist, and promote perpetual adoration to the Blessed Sacrament, offering, as far as possible, the Chaplet to The Divine Mercy every hour for the dying.

• Bring the message of The Divine Mercy and its devotion to a suffering world, according to the revelations granted to the Church through Saint Faustina.​​​​​Bring the Chaplet of The Divine Mercy to the sick in hospitals and homes, promotes the Eucharistic Adoration. We offer home visits every Thursday at 7:00 PM, we pray for any special needs that families have.

As growth and formation in the faith, we form small groups called Cenacles, which meet biweekly in the Church.

Each member is encouraged to put their faith into practice through the spiritual and corporal works of mercy.

Come and join us! We are a prayer group that offers an atmosphere of joy and prayer that facilitates a personal pentecost with all its transformation effects, aided by the presence and power of the Holy Spirit.

We also offer an annual congress of evangelization, classes of life in the Spirit and spiritual growth courses to have a greater knowledge of your faith as Catholics, as well as an annual vigil of Pentecost. We also offer services for funerals, novenaries and prayers to the sick in their homes when they need it.

We are a ministry that offers spiritual growth, emotional support, and prayer. More than anything we help people to know more about our Mother Mary.

We invite the community when they need the Rosary to be prayed at their homes for any intention, need, death of a loved one or to enthrone the Sacred Heart of Jesus in their homes.

We are available for these services any day of the week preferably in the afternoon. We are just asking to please notify us with 2-3 days in advance.
