G12 Vision

Our style of church is based on the discipleship and mentoring model Jesus shows us in the New Testament. 

We reckon this way of doing church means that no-one gets overlooked, and everyone has a chance to live the life God planned for them to the fullest. 

That's why we often talk about the real life of the church being in the city groups. In that smaller setting, relationships  can be built with leaders that care deeply about you and your family, and can help you grow in your faith.

The G12 vision is basically the best way of doing this that we've come across.  

If you'd like to know more about how this vision is impacting generations across the world with the gospel,

please do feel free to have a chat with any of the leaders, any time.

Pastor CéSAR & Claudia

Pastor César has written many books about the vision and is a renowned international speaker. The Castellanos’ have four daughters, a son and five grandchildren, with all the family involved in ministry. 

Pastor Claudia Castellanos has faithfully served alongside her husband since the birth of MCI. Leading one of the largest networks of women in the world, she is responsible for over 20,000 cell groups in Bogotà. As well as her pastoral duties, she has also served as the Ambassador of Colombia to Brazil and was a Senator for the Republic of Colombia from 2006-10.


Thousands of churches from around the world have adopted the G12 vision as a means of building the church and spreading the gospel. From small churches in Sri Lanka starting out in the vision, to churches such as Faith Community Baptist Church in Singapore with 10,000 members, G12 has equipped churches of different sizes and denominations to be fruitful and multiply.

The G12 community gathers throughout the year at regional and international conferences, which you can find out more about here.

The UK hosts its very own G12 conference each year. It's a great opportunity for the G12 churches in the UK to come together, be encouraged by one another and receive some great teaching from Pastors and Leaders working within the vision from around the world.

History of G12

In 1983, Pastor César Castellanos felt God tell him to take a vacation to the coast, which he didn’t believe he could afford at the time, but he trusted in God. It was during this holiday that the Lord spoke to him and gave a vision of a church of thousands.

A month later in Bogotà, Colombia, Pastor César and his wife Claudia founded a church, starting with only eight people in the living room of their home. Today the church has over 200,000 members.

The church grew as Pastor César followed Jesus’ example of building the church on a foundation of 12 disciples. God spoke to him saying, “If you train 12 people and are able to reproduce the character of Christ in each of them and if they in turn are able to do the same with another 12 and so on, then the church will experience unprecedented growth.”

Today the influence of a church that had such humble beginnings in Bogotá, Colombia extends all over the world. It is now one of the fastest growing churches in the world, holding seven Sunday services.
