Father Bao Thai – Pastor

Telephone: 714-544-3250, Ext. 14


Father Bao Thai was born into a non-baptized family in 1970 in Saigon, South of Vietnam. Through an incredible series of events, he and his entire family converted to Catholicism nine years later on the feast day of the Solemnity of Our Lady’s Assumption, 8/15/1979.

After earning a B.Sc. in Computer Science from Saigon University (May 1992) and teaching at a high school for an academic year, he left Vietnam for Orange County in July 1993. In August 1995, he answered God’s calling and a yearning desire. He broke new ground when he entered Mount Angel Seminary in Oregon, where he obtained a B.A. in Philosophy (May 1998), and he continued on to obtain his M.Div. and M.A. in Spiritual Theology (St. John’s Seminary in Camarillo, May 2003), as well as his Licentiate of Sacred Theology (S.T.L.) in Spirituality (The Pontifical University of St. Thomas Aquinas – the Angelicum in Rome, June 2009).

Grounded in his faith, learning, and hard work, Father Bao has enthusiastically served God’s people. After his ordination to the priesthood of Jesus Christ at St. Columban on June 7, 2003, he has served at San Francisco Solano, St. Anthony Claret, Holy Family Cathedral and Our Lady of La Vang. He has come to St. Cecilia since July 1, 2015. On Sunday, November 19, 2017, Bishop Kevin Vann installed Fr. Bao as the 7th pastor of St. Cecilia Church and School.

Telephone: 714-544-3250, Ext. 15


Deacon Erialdo Ramirez Alfaro begins his very first assignment in his ministerial life with us here at  St. Cecilia on July 1, 2019. He has been chosen to replace Fr. Ismael as our 2nd parochial vicar. Soon-to-be Father Erialdo Ramírez Alfaro is 29 years old. He was born on August 16, 1989 in Guadalajara Jalisco, Mexico. His parents are Erialdo Ramirez and Mireya Alfaro. He has 3 siblings, Mireya (twin sister), Alejandro and Barbara. Dcn. Erialdo comes from a long line of dentists— his grandfather to his mother, his uncles, his cousins and all his siblings ​​are graduate dentists . Only four of his relatives from his mother’s side chose another profession.

When he was young, he encountered the Lord through the daily reading of the Scriptures and prayer. From this, he heard God’s call to the priesthood. One of his grandfather’s patients was a mother of a missionary priest in Africa and Asia and she always brought to her appointments the monthly magazine of the missionaries and Dr. Rogelio Alfaro gave one to his grandson, Dcn. Erialdo, and since then he fell in love with missionary priesthood. After experiencing different missionary seminaries, he entered the Diocesan Seminary of Guadalajara in 2007 where he studied 5 years of philosophy and obtained a bachelors degree and a license in sacred philosophy.  Later, he entered Saint Joseph’s Seminary in the Archdiocese of New York, where he completed one year of English and three years of theology.

In 2016, he joined the Diocese of Orange, where he has many relatives on his father’s side, and finished his priestly formation in 2018. He was assigned a Pastoral Year as a Deacon at Saint Mary’s Church in Fullerton. He will be ordained as a priest on July 27th at Christ’s Cathedral at 10:00 am. Dcn. Erialdo greatly enjoys working with the ongoing formation of Catholics. In September, he will teach Faith Study Classes in English every Wednesday at 9:30 am in the School Library and in Spanish every Tuesday at 7:00 pm in the Kuper Center. Please don’t hesitate to introduce yourselves to Dcn. Erialdo and in case you find it difficult to pronounce his name, you may call him Deacon Eric. After his priestly ordination on Saturday, July 27, we will have the joyful privilege of calling him Father Eric. By that time, we humbly say that our St. Cecilia’s Parish will have been very blessed to have two newly ordained priests serving as young, talented, humble, fervent and caring parochial vicars: Father Nicolaus (ordained in June 11, 2016) and Father Eric. He is excited to work with our entire parish with an open heart and an attitude of service and listening for all those who approach him and are faithful of St. Cecilia Church and School. We are looking forward to welcoming, knowing and working with Dcn. Eric, soon-to-be Fr. Eric!

Ahora es diácono de transición y realiza su asignación pastoral en la iglesia de Santa María en Fullerton e inmediatamente después de su ordenación sacerdotal el sábado 27 de julio tendremos el gozo glorioso de llamarlo Padre Erialdo. En ese momento decimos humildemente que la iglesia y la escuela de Santa Cecilia han sido muy bendecidos por tener el total de dos sacerdotes recién ordenados que vienen a nosotros como jóvenes, talentosos, humildes, fervientes y cariñosos Vicarios parroquiales: el padre Nicolaus (ordenado en junio 11, 2016) y el padre Erialdo.

Solo cuatro de sus familiares del lado de su madre escogieron otra profesión. El P. Erialdo escuchó por primera vez el llamado de Dios al sacerdocio cuando tenía 13 años de edad. De joven le gustaba mucho leer las Escrituras y de estudiar el Catecismo y especialmente de participar en la Santa Misa en su parroquia. Una de las pacientes de su abuelo era madre de un sacerdote misionero, y le llevaba al Dr. Rogelio Alfaro a cada cita una copia de la revista mensual de los misioneros de la congregación de su hijo, un día le dio una de estas revistas a su nieto Erialdo y él quedó fascinado con ser sacerdote misionero. Así, después de tener varias experiencias con diferentes congregaciones de misioneros, entró al Seminario Diocesano de Guadalajara en el 2007 y ahí estudió 5 años y obtuvo un bachillerato y una licenciatura en sagrada filosofía, después ingresó en el Seminario de San José en la Arquidiócesis de Nueva York donde completó un año de inglés y tres de teología.

Dear Brothers and Sisters in Christ,

God’s love be with each of you this beautiful weekend!

On behalf of my wife, Carrie and our son, Brendan Michael, I wish to thank you for welcoming us into this wonderful community here at St. Cecilia’s. Over the past few months, we have experienced God’s most joyous spirit alive and well in each of you. We have witnessed how God created you in His likeness and image calling you to be His lights in the world today. May you continue to transform it for the greater glory of His Holy name!

Just a little about myself and our family. I was born and raised in the small fishing community of San Pedro near the Port of Los Angeles. I am the youngest of five children – four of which were girls. I am the product of Catholic education having graduated from Loyola Marymount University where I received my Bachelor’s Degree in Business Administration, as well as my Masters of Art Degree in Education. I currently hold a teaching credential here in the State of California, including several professional certifications in Human Resource Management and Accounting. I moved to Orange County in the summer of 2002 and met the love of my life, Carrie, in 2003. We entered into the bonds of holy matrimony in 2004 praising God for uniting us in His love. In 2008, we received the gift of Brendan Michael who now keeps us very busy and on our toes. We have two more (2) loves – Penny ( a Jack Russell Terrier) and Gadget ( a Beagle ) – who also give us a lot joy and laughter. We have been very active in our faith having served in such ministries as Cursillo, Marriage Preparation, Eucharistic ministry, Sacristy Ministry, Jail Ministry, Lector Ministry and have been active members of our local church’s Pastoral & Finance Councils. We are excited to now be a part of this very dynamic parish and cannot wait to become more involved in parish life with each of you!

Today, Jesus, is asking us to view life from various vantage points and to learn from them. He is calling us to treat each other as we would want to be treated – living the Golden Rule. He is our role model on how to love God and love our neighbor. He tells us in the Acts of the Apostles that “there is more happiness in giving than receiving.”

There is no doubt that in today’s world we are busy. Sometimes we are so busy that we forget to focus on that which is most important – loving each other. I know that I forget far too often than I want to admit. But, it’s not too late. We can begin today taking small steps to express God’s love through caring for and sharing with our neighbor. Maybe it can be praying as a family for the needs of others; visiting someone who is sick or homebound; making a meal for someone who needs it the most; providing clothing or shelter to someone who has none or even just being a friend to someone during a difficulty time. Just maybe, by being DOERS of the Lord, we can change our small corner of the world here in Orange County and allow God’s love to abound everywhere. My brothers and sisters, GIVE SO THAT YOU MIGHT LIVE IN HIM ALWAYS!

Your humble servant in Christ,
Deacon Bill Weeks
