Commencement Speakers: Models of Engagement with the Culture

I wonder if there are at least two (and perhaps more) different models (or emphases) at work in our conversation about commencement speakers:  

 

1. Emphasize clarity (“purity”) so as to minimize confusion and engage the culture from a position of strong identity

 

2. Emphasize dialogue with difference so as to engage the culture from a stance of openness to exchange and growth in mutual understanding 

 

I think that both of these approaches have distinct strengths and weaknesses; and both can find strong grounding in the CST tradition.  My question is whether within the expanse of Catholic education in the United States we might want to encourage a variety of models engagement (perhaps with a baseline and a ceiling, but with quite a bit of room for difference) with the culture.  Rick, do you agree?
