If you want to choose the right church, use the Bible yourself.
Jesus only built one church - Matt 16:18.
That church has not faded away as Christ said it would not - Matt 16:18.
How do we know what we should and should not be doing?
Use the examples of the church Christ built, found in the pages of the New Testament.
- They met together on the first day of the week - Acts 20:7
- They prayed, sang, and taught - Acts 2:42, ,Col 3:16, Eph 5:19.
- They partook of the Lord's supper EVERY first day of the week - Acts 20:7; I Cor 11:23-29.
- They gave as they prospered Every first day - I Cor 16:1-2.
- They were told they must have unity in what they taught and practiced- I Cor 1:10, Gal 1:8,9.
Some choose to partake of the Lord's supper other than on the first day of the week, or carry it out quarterly. This is not found anywhere the New Testament, therefore the practice has no authority from God.
Some choose to take up offerings on days other than the first, again no example of the church every doing so, therefore, no authority.
Some use mechanical instruments of music while singing, again not found in the New Testament of which we are under.
When things are being done that is not authorized by the Bible, it should raise a red flag to you.
The congregations of the New Testament, Corinthians, Ephesians, Romans, etc, were not different churches with different teachings and practices, they were all part of the one church that Christ built and practiced the same thing, they were only different congregations of the one church - Eph 1:22-23, 4:4.
They did not uphold any of the Old Testament, seeing the Law of Moses was ALL nailed to the cross at Christ's death, and taken away - Col 2:14.
It is forbidden in the Bible for Christians to hold to any part of the Law.
So everyone does claim to be the right church and "Strictly Bible".
Thanks be to God that you can have your own Bible, and you can see what the Lords church is and compare the teaching to the practices of whatever church your looking into.
When people do not practice what the 1st century church did, then they are not using the Bible as there only authority, if they practice something that we cannot find in the Bible, then they are adding to the Bible with man made doctrines and practices - Matt 15:9.
The Bible must be the only authority in the church (or religion for that matter) - Lk 16:15; Gal 1:8-10; II Tim 3:16.
The work of the church is to glorify God and save souls, not glorify and please ourselves with man-made additions.
