I’d say even deciding to trust another is thinking for oneself. People might say “I trust the Church” but that is a decision they have made themselves, just as others will say “I trust the Q,ran”. Of course upbringing is extremely influential in who we trust, but we still have to give consent to continuing our cultural upbringing.
Even when we say “I trust X”, I think I see a lot of “filtering” going on - everyone also comes with, for example, political and national paradigms that come in to play. When Papa Francesco, for example, says he’d like to see a poor Church for poor people - lots of people who say they trust the Pope will find a way of viewing that in a way that is comfortable for the rest of their views and life. Few people totally abandon themselves to other’s and when that does happen it well may be quite dangerous (such as the followers of David Koresh or Jim Jones). I think we even struggle to fully trust Jesus and what he taught - we often find ways of sanitizing it a little so we can still enjoy a certain level of lifestyle (with a few notable, wonderful and inspiring exceptions such as Francesco of Assisi).
