Mother Teresa - A Valid Comparison?

Is it just me, or does the view of Mother Teresa presented in THIS POST concern you?

Up until today, I haven't read any of the recent discussion on Mother Teresa's apparent "crisis of faith"--mainly because I've never had good reason to consider her a genuine believer. Consequently, it didn't surprise or interest me that she struggled to understand and embrace the God of the Bible--she embraced a system (Roman Catholic church), rather than a Savior.

To me, including Mother Teresa in the company of Ruth and Naomi (as done in the linked post) is at best distracting, and at the worst implies a spiritual position Biblically unsupportable.

I'd like to hear from you on this! I want to be (need to be) charitable but believe I must also guard against our present-day "inclusiveness/tolerance" within the Church.
