The function of the church most certainly has changed. This is what was experienced at Corinth in the second half of the first century:
What then shall we say, brothers and sisters? When you come together, each of you has a hymn, or a word of instruction, a revelation, a tongue or an interpretation. Everything must be done so that the church may be built up (I Cor 14:26 NIV).
It very quickly became hierarchical to the point where 1 Cor 14:26 is far removed from the function of the church in most of contemporary Australia where I live.
The church function has changed radically. Is that not the case in your part of the world?
