Thank you for your comments too, Lifeisawesome

And I know well your concerns . . . for you hint at it in almost every post. I just hope it does not make you fearful to approach our Lord in the “acquired” way described in this thread . . . for we are all called to do so. And, God willing, it can lead to the infused. As St. Teresa says, recollection is the quickest and surest path to the prayer of quiet.
To clarify (in case it’s needed), I was simply echoing Bookcat’s comments that some writers feel the need to make distinctions (ie, acquired vs infused) . . . others don’t. The experience of contemplation and the study of it are two very different things . . . and the words we use rarely do it justice as the Saints often lament. But the failure of words has never stopped writers from coming up with different ways of describing various aspects of the contemplative experience. “Acquired” might be a fairly modern term in the scheme of things . . . but it expresses very ancient concepts. For some people distinctions like this are helpful . . . for others not.
I’m a Carmelite so the great joy of my life is parsing things in the manner of the Saints of my order . . . recollection, quiet, union, active, passive, purgative, illuminative, unitive and what not. However, the experience of it is not so discrete, linear and step-by-step it might come across when looked at from a purely academic point of view. Distinctions fade . . . acquired or infused; it doesn’t matter for they are but seperate sides of the same coin.
The heart knows these things . . . and if the mind asserts itself to much then the love affair between Christ and the soul takes on an introspective and analytical approach that snuffs out the deep type of prayer these Saints describe. Thinking to much in prayer rather than simply loving (to paraphrase St. Teresa) leads one to believe it can manage things through process . . . and we risk approaching God like Joe Buck calling color commentary: the 30, the 20, the 10 . . . touchdown!
Study and actual prayer are two different things . . . the former often just a pale reflection of the latter. One relies on distinctions . . . the other doesn’t. This is the point I was trying to make.
Blessings and peace,
Dave
