10 Reasons to Become...
Remain a Catholic

It is not unusual for people to ask “Why are you Catholic?”  If your response is a blank stare or “because that was the way I was raised” or even if you think you have a good answer to this question, we guarantee you will benefit from attending this dynamic event.In his light-hearted and fast-paced presentation, Father Mark will share with us his top 10 reasons for becoming and remaining a Catholic.

In 1990, Mark Wiesner entered St. Patrick’s Seminary in Menlo Park, California, and was ordained a priest for the Diocese of Oakland in his home parish of St. Francis of Assisi, in Concord, CA, on June 10, 1995. After his ordination, he was assigned to several parishes in the Diocese of Oakland before becoming pastor of St. Charles Borromeo Parish in Livermore, California, in 2012.

Due to his amazing talents, Father Mark has served the Diocese of Oakland far beyond his pastorial duties. During the Great Jubilee Year of 2000, Father Mark was responsible for the Diocesan liturgy which culminated the celebration of the Jubilee Year for the Diocese of Oaklandon November 11, 2000. Participating in the Eucharistic Liturgy were Bishop John Cummins, more than 400 clergy, a choir of 600, a full orchestra, and an assembly of nearly 18,000 Catholics from throughout the Diocese.

In 2016, during the Extraordinary Jubilee Year of Mercy, Fr. Mark was commissioned by the Holy Father on Ash Wednesday as a Missionary of Mercy for the Holy Year. When the Holy year concluded, Pope Francis decided the Missionaries of Mercy should continue their work, and so Fr. Mark continues in this role until today.

In addition to ministry, Father Mark is a trained working voice over artist, and performs annually with many local theater groups, being in the cast of more than 60 musicals over his lifetime. He is passionate about conducting retreats, parish missions, days and evenings of reflection and teaching scripture. His homilies can be heard at www.stcharleslivermore.org.
