In that case you're mixing psychological terms in with theological terms in your list as well as your answer.
The point I am trying to make is to non-theologians, so I am mixing terms. "Separated brethren" is perceived as more "positive" than "heretic." The Sacrament of "reconciliation" is more positive than "penance."
Also, please clarify what you mean by "It is also misleading to be overly positive, as it is not objective nor realistic"?
We are to strive toward the object (which is God and how HE views things). God is the object. We are the subjects. The purpose of our spiritual life is to unify us with God as best as possible. We should show "hope" (and faith and charity), but to be overly "positive" when being realistic calls for a different response is merely delusionary. For example, if I saw a car headed for my 2-year-old son in the road, I could say, "Oh, I'll just be positive and calmly let him know he is about to die," then when he gets hit and killed, perhaps I would have wished I might have SCREAMED "LOOK OUT" at the top of my lungs so he would have moved.
Which one is "positive"? Screaming at my son. Get it?
Are you a theologian? And, who the hell cares if one term is more "positive" than another term if they both express the same reality? Oh, I guess the guy who wants to view Protestants as evil people use the term "heretic."
"Sacrament of Reconciliation" is the name for that sacrament now used by the Church.
Positive people are not unrealistic; they can often see solutions where the pessimist simply gives up.
For instance, in the example you use, a positive person would be shoving the child out of the path of the car, whereas the negative person just stands there and yells at the kid, as you did in your example.
Get it?
