There are no “rituals”. A personal relationship with Jesus, with guidance from the Holy Spirit and prayer and praise to the Father using the “power of Attorney” (in Jesus name) given to us by grace is the privilege of a Christian. New believers and children of believers are baptized and reverent partaking of The Lords Supper according to the instructions given by Jesus.
The “church” is the collection of believers, not some organized institutional hierarchy. When “rituals” replace a personal relationship legalism replaces grace.
