John Maxwell is a theologist. OSE does not need theology or a strong leader. A OSE community does need a democratic constitution and a commited community to progres by it. If there is a common vision and a constitution then it does not need a strong and powerful leader. But democracy is essential and official offices should be assigned by elections. Also decisions should be taken by voting. OSE has yet to develop in this respect. (check also the open source debian linux community which has democratic rules) Strong leaders always tend to want to keep and expand their power until they are corrupted by egomania and often can only be removed by violence or collapse of their movement. Civilization has passed that. In a democracy, where the people do not only elect representatives for limited time (as in republic democracies) but also directly decide on important questions by voting (as in direct democracies), strong leaders cannot accumulate inappropriate power and are not needed in the first place. All they can and should do is to encourage and influence the political discussion. But the power remains in the hands of the people. To keep it that way the power of a democratic government should be split into 4 independent areas.
A) the legislative (parliaments creating laws, subject to approval by the people, members subject to election),
B) the executive (executing the laws and conducting the state businesses issuing and managing currency, subject to election by people or legislative),
C) the judiciary (courts and judges deciding what is or is not violating the laws, subject to election by people or legislative),
D) free (e.g. source protection) and independent media to inform the voting people (also on government corruption) so they can perform educated voting and election.
