Jerry Hill, on his perspective on church buildings and what they did in Guatemala:
Where do church buildings fit in? They are not mentioned in the New Testament. With “all creation” as the goal, God’s army moved swiftly over the earth, leaving behind Christ’s church meeting in homes. Financial resources went to preaching and to helping circumstance-stricken people. World evangelism was accomplished. Since then, our systems have not duplicated that all-important feat. Respectfully speaking, church buildings and the struggle to get the gospel to every human are comparable to a pentagonal, permanent structure in Washington and the invasion of Normandy. I think a better question would be, How fast do you want to move? In our preaching in Guatemala, we opted to leave the decision of a meeting place up to the troops.
From his book on the first years of their work in Guatemala, unavailable on the internet or in print form, as far as we could discover.
