There’s nothing wrong with traditional methods of doing church. As long as you want to minister to traditional church members.
Traditionalists (whatever your tradition may be) need places to worship, learn and be discipled. Too many of them have felt overlooked, even ridiculed, in recent years as many churches have rushed to make changes.
The traditional church member is dying out.
If we truly want to change the world with the Gospel of Jesus, that is less likely to be done using traditional church methods with every passing year.
