Welcome to the official website for Christian Service Training Institute. CSTI is a four-year, full course-of-study Bible curriculum, sponsored by the churches of Section One of the Southern California District of the United Pentecostal Church International. 

2 Tim 2:15 - Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.

These pastors and ministers have co-opped together for 35 years, demonstrating the ongoing hunger of the church members for the Word of the Lord and the unity and trust of the ministry toward one another. This has been an incredible blessing to both saint and church alike.

Please browse through the site and discover some details about CSTI. You'll find the courses of study, the dates and times and on-campus location of the classes, the costs involved, and how to enroll and access the courses if you are an "Internet Enrollee."

All classes are audio and video recorded, along with the handouts and PowerPoint presentations. They are posted on this web site (password protected after the 2nd week), giving the Internet Student full access opportunity. Please check this out and take advantage.

Past courses are now available so one can make up with at-home study and avoid a long wait for the missed course to come around again in its cycle.

You will be enriched by the courses and teachers as they impart truth into your soul.
