The early church saw an explosion in growth in the first 300 years. This was despite the fact that the practice of the day was to:
- Limit the involvement of non-baptized to either nothing or just the initial worship service, keeping them out of the communion dinner and fellowship.
- Baptisms took place only once a year (usually on Easter Sunday). Before baptism they would be interviewed to make sure their faith was sound and deep.
- It often took three years from when a person expressed interest in Christianity to when they were baptized. During this time they would get educated on the specifics of the Christian faith.
