Jews and Gentiles were together, perhaps the worship was not as formal. Worship was different in different churches. We may not know, but it seems probable. In the United States, the worship in different churches is different. Black churches do not worship like white churches.
Hispanic churches worship in a different way than white churches.
Worship is not the same. Worship here is different, and not merely in language. We must recognize the differences, and appreciate, respect, and honor one another. My structure does not overrule your structure, my methods do not overrule your methods. If you consider the Bible, there is spontaneity in worship.
