Laws of Church Growth and Decline
Laws of Church Growth and Decline
Wesley’s Law of the Decay of Pure Religion
Although the "law" originates with John Wesley the founder of Methodism, it was gievn the status of law by Dean Kelley in Why Conservative Churches are Growing (see page 105). His version can be summarised as: "Taking up the religion has produced benefits which makes missionary zeal too costly to engage in". Essentially as people grow in grace they grow in respect and wealth making evangelism and enthusiasm a threat to their new status. Thus enthusiastic Christians do not stay enthusiastic for long. This law is one of the dynamic hypotheses in the limited enthusiasm model. Kelley and Wesley clearly saw that revivals burn out because of the limited period for which a Christian can remain seriously religious.
Kelley quoted Wesley's original version the law indirectly from Max Weber (The Protestant Ethic and the Spirit of Capitalism, chapter 5) "I fear, wherever riches have increased, the essence of religion has decreased in the same proportion. Therefore I do not see how it is possible in the nature of things for any revival of religion to continue long. For religion must necessarily produce both industry and frugality, and these cannot but produce riches. But as riches increase, so will pride, anger, and love of the world in all its branches." Weber quotes Southey, Life of Wesley, chap. xxix. For more information see the article on origin of Wesley's Law.
Kelley's Thesis on Strictness and Strength
Strict churches are strong and more likely to grow compared with lenient churches which are weak and more likely to decline. (Dean Kelley, Why Conservative Churches are Growing).
The thesis has proved controversial since it was proposed in the 70's with attempts to refute and defend it. The arguments in its favour are that churches that are strict in their beliefs will offer a stronger and more desirable version of the faith. Thus they command more enthusiastic and committedsupport, a greater desire to see others converted, and a more attractive and certain set of beliefs
Laws from the Limited Enthusiasm Model
Diffusion Law
As a church grows the pool of potential converts shrinks and the church finds it increasingly harder to make converts due to increasing time spent on its own people, in comparison with evangelism.
Law of Limited Enthusiasm
Churches grow through enthusiasts who not only make converts but new enthusiasts. Enthusiasts only retain their potential to recruit for a limited period, thus church growth depends on their ability to reproduce themselves.
Law of Revival Growth
If the ability of enthusiasts to reproduce themselves is above a threshold depending on the losses from the church and the number of potential converts, then rapid revival growth in the church will occur.
Law of Extinction
If the ability of enthusiasts to reproduce themselves is below a threshold depending on the losses from the church, then a church will not sustain itself at any level but become extinct.
Law of Growing Populations
In a growing population the thresholds of extinction and revival growth are lowered. Thus church survival and revival growth are more likely in a growing population.
Law of Renewal
If a church makes enthusiasts from renewing existing believers, revival growth can be achieved even if the church is otherwise not converting sufficient people, providing there are critical masses of enthusiasts and church numbers.
Law of Spiritual Life
The spiritual life of believers can be enhanced by them engaging in corporate spiritual activity leading to them being more effective in conversion.
Laws Drawn From Other Disciplines
Michels' Iron Law of Oligarchy
As organisations grow and mature they develop oligarchies due to the tendency of leaders to organise the structure to consolidate their interests. This makes it harder for people to get involved leading to less enthusiasm and lower recruitment and retention. Proposed by sociologist Robert Michels'in Political Parties. Limits to growth were secondary to his concerns, but political scientists have used it as one reasons why politicalparties stop growing. For churches this could be expressed in their tendencies to develop into different classes of priests and laity, making it harder to recruit, involve and retain laity.
Olson’s Law of Free Riding
The larger an organisation grows the higher the opportunity for free-riding; the people who benefit from the organisation but do not contribute. This makes it harder for the organisation to grow as more resources need to diverted to benefit the free-riders with less resources available for recruitment. Due to Mancur Olson, The Logic of Collective Action. He applied it to general organisationsof people and has been used by political scientists as another reason for the difficulty political parties have in growing. For church growth it would mean that larger churches have a greater proportion of people who benefit without contributing, thus slowing their growth.
Law of Organisational Complexity
As churches grow in numbers the people and physical plant become more complex, diverting time from evangelism and recruitment, towards maintenance. This law is not about free-riding but about the increasing demands of larger churches leaving less time for evangelism. The effects of this law can be reduced by good organisation and delegation on the part of the church (see below). There is a reverse effect that as a church declines but its physical plant stays the same the dwindling number of members have to devote more of their time to the physical resource and thus less time for evangelism.
Tan’s Law of Positive Complexity
If an organisation can respond to its growth by creating efficient structures to mobilise its people, its growth can be enhanced due to the provision of specialist benefits not available in smaller organisations. This can counter the effect of free-riding and organisational complexity. Discovered empirically by Alexander Tan a political scientist (1998). In church terms this means that big churches can provide more benefits than smaller ones and thus be more attractive and hence recruit and retain more people.
Laws from Sociology of Religion
Olson's Law of Church Friendships - The "Club" Effect
As churches grow so does the quality of the friendships in the church thus making it harder for new people to join and integrate. The desire to benefit from existing friendships exceeds the cost required to recruit new people. (Due to Daniel Olson, Church Friendships, Boom or Bust?)
Secularisation Hypothesis
As society progresses religion loses its authority in all aspects of social life and governance. This has been interpreted in a number of ways
1. Rise in economic development and wealth leads to a decline in the demand for religion.
2. A rise in education and knowledge leads to a decline in the demand for religion.
These are not the same. The first implies wealth is a competitor for time, the second that religion is for those who have a limited view of reality. Different people interpret “progress” in different ways: wealth, economic development, science, education, political and social freedom.
Principle of Inappropriate Supply
Churches can decline due to their failure to supply the spiritual needs of society rather than the lack of spiritual demand in society. (Stark and Iannaccone). This was proposed to counter the secularisation hypothesis. The decline of religion's role in society is not the same as a decline in demand. Its role could decline due to religion being unable to meet the supply, or for other reasons.
Miscellaneous Laws
Wimber's Law of Friends
People who join a church stay there mainly because they make friends. Often said by John WImber after his experience as a church growth consultant. He probably did not originate it but did much to popularise it.
Principle of Divine Revelation
Also known as the principle to restore your sanity after all the other church growth laws! "Truth cannot be determined by reason and experiment alone, it requires divine revelation and faith". In the words of Billy Graham “What does the Bible say?”
