Salvation doesn't have anything to do with the religion which we belongs to but by how good and obedient we are to God. True salvation comes from believing in Christ, repenting of sin, and obeying His teachings, not merely identifying with a religious group.
The bible teaches us to always come together and talk about God and the goodness He have done in our life. A community of believers can help strengthen a person's relationship with God, but it is Christ alone who saves. Therefore, religion without genuine faith and obedience cannot save, while a sincere relationship with Jesus Christ leads to eternal life.
