Please meet Reverend Randy Guillen, our new Parochial Vicar. Fr. Randy is close to sixty years old and has been in the priesthood for more than twenty-six years. He comes to Mission Parish from his previous post at the Administrator of St. Angela Merici Parish and School. His hometown is Santa Ana and his favorite area of ministry is evangelization. His favorite television show is Family Affair and his favorite travel destinations are Italy and Spain.

Father Randy’s Favorite Scripture is from 1 Corinthians 12, “Now in regard to spiritual gifts, brothers, I do not want you to be unaware. You know how, when you were pagans, you were constantly attracted and led away to mute idols. Therefore, I tell you that nobody speaking by the spirit of God says, “Jesus be accursed.” And no one can say, “Jesus is Lord,” except by the Holy Spirit. There are different kinds of spiritual gifts but the same Spirit; there are different forms of service but the same Lord; there are different workings but the same God who produces all of them in everyone…

Now you are Christ’s body, and individually parts of it. Some people God has designated in the church to be, first, apostles; second, prophets; third, teachers; then, mighty deeds; then, gifts of healing, assistance, administration, and varieties of tongues. Are all apostles? Are all prophets? Are all teachers? Do all work mighty deeds? Do all have gifts of healing? Do all speak in tongues? Do all interpret? Strive eagerly for the greatest spiritual gifts.”
