This took me much too long to figure out. It never hurts to re-explain why the Church of Jesus Christ of Latter-day Saints uses the programs of the Boy Scouts of America for their boys and young men. In Aaronic Priesthood quorums (the target for most of Boy Scouting and Venturing), the objective of all activities (including Scouting) is to strengthen testimonies and fulfill the purposes of the Aaronic Priesthood. The great reason for Scouting is that it is perfectly suited for this task, and Venturing is the RIGHT tool for the priests quorum.
Scouting in the Church does not exist simply to provide adventure and experience. It is true, that Scouting provides this. And this is clearly one of the strong appeals that should be there for the youth. After all, "three quarters of Scouting is Outing." But I do not think that this is the greatest strength of the program(s). It is the opportunity to use these adventures to help young men develop personally.
To be complete, I'd want to illustrate how the Church intends for a natural progression of BSA programs for their young men. This would likely include a brief outline of the Boy Scouting program, Varsity Scouting, and Venturing. I'd show how these programs build upon each other, and that each is a natural progression from the earlier one. This includes the monthly theme of Boy Scouts to the quarterly theme of Varsity Scouts to the flexible program of Venturing. Also, the planning system is progressive, from a patrol/troop system to a team with managers to a committee system. Young men who experience a quality and complete program would have seen a natural progression of abilities in planning and leadership. (This is key to their preparation for the Melchizedek priesthood and future responsibilities, not to mention the worldly advantages it would provide.) I'll leave this for another time.
