- Bishops, leaders of Christian unions
- Pastors of churches, rabbis of congregations
- Directors of Bible schools and leaders of Christian missions
- Ministry leaders
Also pastors/rabbis can bring their assistant pastors.
A number of assistant pastors a pastor can bring is calculated like this:
One assistant pastor per 100 members in a church/congregation
If a church/congregation has only 80 to 100 members, a pastor can bring only one assistant pastor.
Also pastors/rabbis can bring 1-2 prayer ministers. Prayer ministers join in the prayer for the retreat, but they cannot attend the main sessions.
