Since the mid 70’s, there has been a significant influx of Christians from South India into the United States of America. Finding us in the midst of great diversity with differences in language, culture and lifestyle, we, the Christians who follow the time tested faith and practices of the Church of South India, felt a growing need to be culturally and religiously bound together by the liturgical and ecclesiastical practices of the Church of South India. It is our vision that St. Peter’s CSI Church will cater to the spiritual needs of its members by providing a platform for orderly practice of the faith.

We, the baptized members of the Church of South India, that do confide in the one foundation of the Church, the body of Jesus Christ the Lord, in whom the Word became flesh and to whom the Scriptures bear witness, aim to unite together to preach the Word, administer the sacraments, and fulfill the calling to glorify the triune God, the Father, the Son and the Holy Spirit.

Our vision is to touch the world with the Word of God through its members. So we strive to be a strong community of faith in Christ, through whom the Word became flesh. We are motivated by a passion for God and compassion for people. As a growing church, its message is to call upon everyone to depend on God’s Love, guidance and strength in every step of the way.

Founded on May 29th 2004, to minister to the pastoral needs of the greater metropolis of Los Angeles and beyond, the congregation is going from strength to strength. Tilll today God has blessed the church immensely. The greatest strength of our church is the openness and cohesiveness of our members which creates a family atmosphere in our congregation. The members do care for each other and treat each other as extended families. Our worship location from Jan, 2004 – June 2013 was St. Paul’s Episcopal Church (1221 Wass St, Tustin, CA 92870) and from July 1st, 2013 forward is St. Thomas Episcopal Church, (15694 Tetley St, La Puente, CA 91745). We were made to feel very homely in these facilities. We are very thankful to the Vicar and parishioners of St. Thomas for their whole hearted support they are providing presently.

We conduct Holy Communion service in English on first, third and fifth Sundays and in Malayalam on second and fourth Sundays of every month. Our Youth take greater participation in the leadership especially on the fifth Sundays. We have an active Choir, Men’s and Women’s Fellowship, and youth groups. Our pride is our very dynamic Sunday School for our children which focuses on the Christian nurture and education of them.

Our achen Rev. Dr. George Oommen provides excellent pastoral leadership and guidance to church and we have seen tremendous growth and stabilization of activities under the very able and blessed leadership of our Achen.

We are very much integrated into the ecumenical and the missional responsibility of the Church. Our Mission Sunday generates support for various missionary, developmental and charitable activities both in India and the USA. In this mission task, St. Peter’s wants not only to be receivers of God’s love and blessings but also be the givers of God’s love and grace to all.

Church actively supports various mission projects. Recently St. Peter’s supported the following missions: Mysore Mission which started in 1995, Bethel Ashram, a centre for the the upliftment of women and mission among women, Asha Bahavan Respite Care Centre, a centre for the Mentally and Physically challenged girls, Samaritan's Purse International Relief. We set apart 20% from the amount collected for mission as a ‘Mission Endowment Fund'. It will be carried over every year and can be used for any special needs related to relief or charity.
