While there was considerable continuity in American Christianity between 1800 and 1960, the past four decades have been marked by an unprecedented degree of discontinuity. One example is the rise of the Made-in-America church.
Congregations of European origins, including most Protestant faiths, often seek ministers who will lead that congregation in attaining its goals. The Made-in-America church tends to be more open to the pastor who challenges people to fulfill the potential that God has placed in that congregation.
