Does Church play a role in Salvation
That’s wrong. Salvation is when God freely gives a spiritually dead person spiritual life (born again). This spiritual life produces faith and repentance towards Jesus Christ.
After salvation you are now enabled to do good by the power of the Holy Spirit who dwells within. Water baptism takes place as an external symbol of your salvation, baptism should most likely happen at the church you are then joining. A church should only accept membership from people who profess the gospel.
