Two religious sisters serving in the Arlington diocese were honored for a combined 115 years of religious life at a special Mass at the Cathedral of St. Thomas More in Arlington Feb. 21.

Franciscan Sister of the Eucharist Mary Timothy Prokes, with residence at St. Philip Church in Falls Church, celebrates 75 years of religious life, and Franciscan Sister of the Immaculate Conception Elizabeth Ann McGuire, who teaches at Bishop Ireton High School in Alexandria, celebrates 40 years.

During the Mass, Sister McGuire renewed her vows before Bishop Michael F. Burbidge. Sister Prokes could not attend.

In his homily, Bishop Burbidge thanked the sisters for their daily “yes” to serving Christ and his church, noting that the Lenten season gives a deeper significance to the day’s celebration.

“That ‘yes’ has required fervent prayer, which the Lenten season invites us to embrace anew. Dear sisters, through a life devoted to prayer, especially before the Blessed Sacrament, you have reminded us that we can never rely on our own powers and resources,” he said.

He added that by living out their vows daily, the two sisters provide all with a holy example during Lent. “In living with integrity your vows of poverty, chastity, and obedience, you reveal the reason for our fasting during this Lenten season: Being reminded that a life focused on the accumulation of worldly and earthly possessions, honors, and rewards can never bring us the happiness we are seeking. Thank you, jubilarians, for reflecting the joy that is ours in a loving and intimate relationship with the Lord lived with simplicity, purity and faithfulness,” he said.

What drew you to the religious life?

My family members who entered religious life modeled for me a most fulfilling life to follow Christ.

What is a favorite family tradition?

My family’s Christmas Eve foods and traditions are a favorite memory. Also, my family was consecrated to the Sacred Heart and on every feast of the Sacred Heart we would have a very special meal, and my mother would turn over the dinner plates and under each one would be a small gift for each of us.

What drew you to the religious life?

While teaching at Hollidaysburg Catholic School in Pennsylvania, there was a change of religious community running the school. The community taking over the leadership of the school was an international congregation from Scotland, the Franciscan Sisters of the Immaculate Conception. In working closely with the new principal, I was drawn toward developing a deeper spirituality. I kept hearing a voice that said, “I want more from you.” The rest is now history and the voice continues.

What are your hobbies, or favorite family or cultural tradition?

I enjoy cooking, baking, working jigsaw puzzles, doing other paper and pencil puzzles, and taking care of my patio and house plants.  

What is one of your fondest memories of your time as a religious sister so far?

My fondest memory is that of becoming my mother’s Godmother shortly before her death. My second is my father’s joy at my final profession.
