Becoming Catholic (OCIA)

Our program formally begins in September following the traditional time-line of the early Church when people were brought into the faith community at Easter, but before then we are gathering with those who are interested through the Summer to begin this journey.  For more information email [email protected] 


< CONTEXT.  This statement is that the Catholic Church is both human and divine. In the Order of Chrisitan Initiation for Adults (OCIA, formerly RCIA), we'll never make the case that Catholics have been perfect. The Catholic Church has never been--nor will it ever be--perfect because as a human institution it is comprised of imperfect human beings, from the faults of its founders (e.g., St. Peter denies Christ three times) to its leaders today. But the Catholic Church transcends its human imperfections because of God's grace that resides there. Christ didn't choose the gifted; He gifted the chosen!

"No one will force you to stay. Have a look at the Catholic Church from inside the convictions that make Catholicism what it is. Walk around in it. See how it feels. Then decide what you think about it."  ~ George Weigel

WHAT MAKES ONE A CATHOLIC? A person is said to be fully initiated in the Catholic Church when s/he has received the three sacraments of Christian initiation:  Baptism, Confirmation and Eucharist. This is achieved through a process of preparation that we call the Order of Christian Initiation for Adults (OCIA) explained below.

COST. We ask that you obtain your own study materials that include:
__ Please get a copy of The New Catholic Answer Bible that we'll be using; this one specifically has embedded explanations of Catholic beliefs.
__ a copy of Brandon Vogt's Why I Am Catholic: and You Should Be Too that relates how the pieces came together for him in his conversion to Catholicism.
__ We will also be making use of the online Compendium of the Catechism of the Catholic Church (or you can buy a paper version)
__ Finally take a couple turns hosting treats for our gatherings
(PS let us know if this is a financial hardship for you at this time and we'll find a remedy).

COMMITMENT. The ask is that you attend as many of the forty sessions on our schedule.

< CONTEXT:  In the name of transperancy, we aim to meet people where they are, but also challenge them to rise up. There's no ladder to heaven except the cross, so we can't sugar-coat things. Catholicism will ask much of you, because Christ asked a lot of us. But it's worth it!

Christ of the Gospels meets people where they were; but he never leaves them where they are. There's so much more in front of us if we're willing to open ourselves to God's calling for our life. So if you're humble enough to know you're imperfect, then consider joining some fellow travelers on this spiritual quest to find out more about of what was established by Christ when he told the man who denied knowing Him: "You are Peter, and on this rock I will build my Church." There's a big adventure waiting for you!

Prayer for Becoming Catholic:  Lord Jesus, we ask your blessings on those who aspire to join your Church through our parish community. As they ponder your Word and share their stories, may the fabric of their lives become interwoven into the very Body of Christ, your Church. Amen.

What is OCIA?  

OCIA stands for Order of Christian Initiation of Adults. When we bring people into the Catholic Church, or help them to receive all of their initial sacraments if they are already baptized Catholic, we call that "initiation." While the word "initiation" is often used when people are talking about joining a club, we are really talking about a process of prayer, reflection and study spread over several months during which the inquirer participates in Catholic life and worship.  The focus of the OCIA process is Christian conversion - a change of heart in which the individual turns toward God and away from whatever is in the way of living a full Christian life. Those who participate in this process of prayer, study and reflection include catechumens (people not yet baptized) and candidates (those already baptized in another Christian tradition) who are joined by their sponsors and others looking to grow their faith. Becoming Catholic today means being a part of an ancient faith, deeply rooted in the teachings and traditions of Christ, that is filled with hope and vibrancy as we continue to spread the Good News of Jesus Christ to all the ends of the earth.

So why Catholic and not some other Christian denomination? One source lists 30,000 denominations of Christianity around the world. For 29,999 of them--if you dig a bit in history--you will be able to identify the human founder, or the person in history who claimed they "knew better" and alleged that the Catholic Church lost its way and now you should follow them instead (you'll find that's the case in this select list of human founders above). Jesus Christ established a Church (singular since He never spoke of the Church as plural), and like most things in our human story we've messed it up with an unending chorus of people saying "I know better." In Matthew 16:18 Jesus said to Simon Peter, "And I say also unto thee, that thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it." From this passage it is very obvious that Christ is the builder or founder of the New Testament church and that he calls this church HIS church. Any church founded by someone other than Christ is not Christ's TRUE church. Other Chrisitan churches might well have parts of the lesser truth, but the greater truth resides in the Roman Catholic Church dated from Pentecost in the year 33AD.
