GREAT COMMISSION TRAINING INSTITUTION (GCTI)
Our vision is to equip reproducible disciple-makers through content, community, contextualized training, and coaching. GCTI provides accessible, affordable leadership development for pastors, lay leaders, women ministers, and bi-vocational leaders to strengthen church health and gospel impact.
Our Mission
-
Provide an online model of certificate or non-certificate programs for church leaders to develop higher-level ministry skills, knowledge, and grow as reproducible disciple-makers.
-
Also:
-
Provide opportunities to serve as teachers/workshop leaders.
-
Provide relational & practical internship and field training.
-
Provide ministry opportunities at GCA churches, church plants, replants, revitalization programs, and pulpit supply.
-
Curriculum
We use the pastors to pastors (P2P) curriculum to train potential leaders, lay leaders, pastors, and women ministers to become reproducible disciple-makers who abide in Christ. The 12-class P2P curriculum includes discipleship, missions and church planting, evangelism, hermeneutics, Old Testament survey, New Testament survey, applied church history, leadership (pastoral/lay ministry), teaching/preaching, theology of the church, theology of God, and theology of Salvation.
We offer a Spanish class on Mondays from 7-8:30pm and an English class on Tuesdays from 7-8:30pm. We have different English and Spanish classes to encourage bilingual students who wish to take two classes during the same term.

Spring 2027 Theology of God
Class Description:
Who is God? We love Him, and we live our lives for Him - but what do we know about this God? And what does it mean that God is one God in three persons? Nothing could be more important than beholding God in his holiness, perfection, and glory. This course will dive deep into what Scripture says about the God who is Father, Son, and Spirit, examining His attributes and how He speaks to us in His word.
Time: Tuesdays at 7 pm (PST)
Duration: A 7-week class meeting once a week starting 1/26/27.
Class Format: This course is delivered entirely online using Zoom. This class contains synchronous (live) and asynchronous (anytime) components. Classes will meet live for weekly, 90-minute online sessions.
Teacher: Brandon O’Sullivan has been in full-time ministry (and a Santa Cruz local) since 2008 - he has led teams in children, student, and young adult ministries. In 2018, he and his wife, Laura, planted Gospel Community Church in Santa Cruz, a thriving young church with a heart to reach the city, equip leaders, and plant churches. Brandon has degrees from The Master's University and Reformed Theological Seminary and is currently finishing a doctorate in leadership from Southern Baptist Theological Seminary. The class content will be different from the first time we taught this class in 2023.
