To be honest, I feel this logo is more like a my personal achievement. This is because I always move and tend to characters that conventional and old when designing logos that related to church or religious.
This logo accommodates the number 12 (from 12 Jesus disciples) and plays a celtic cross, as a negative space, to emphasize the combination of number shapes while giving it a Christian character.
I did not think that in the end the logo became so simple. I hope the simplicity of this logo can make the church look ready for the future without losing its classic character.
