Why have they never been resolved. Don't see tension where it doesn't exist. Don't pigeonhole people due to your own prejudices. Keep all your conclusions tentative and firm them up only when you have an objective basis for confirming them. Redeemed leaders who have walked with God over a long period of time will break molds.
Administrative leaders can be visionary, merciers can discipline.
Do a thorough study of the gifts God provides for Christ's body and understand the temperaments that naturally go with these gifts. Be sure to build your thinking on the Bible. Use this study as an opportunity to build a game plan for how you will equip each leader for whom you are directly responsible. Think through possible situations where your leaders might naturally conflict. Your potential leadership conflicts will vary according to the leaders' various values, and some of them will surprise you.
