When we think of the minimum requirements in various circumstances, it could mean how to cut corners. In this faith, I like to think in terms of the essential requirements.
In church life, many things people think are necessary were never mentioned by Christ. Love for Christ and for one another can even be down the list at times. When we read the Gospels and Acts we must remember that many of the forms of worship we have today had not yet developed.
Somehow they got along without them!
