Lewis 16-18

Chapter 16
Church brings “...people of different classes and psychology together in the kind of unity the Enemy desires.”  Why is this such a problem for Screwtape?  
This leads to a major problem for Screwtape because if people aren't arguing but instead getting along then they start worshiping the "Enemy" more. Screwtape doesn't want people of different classes being a one unity church.
Describe your ideal church.  
My ideal church is a church where the Theology is wholly correct, but they can teach it in an interesting and exciting way. Also, the worship team can also get you pumped up, not that it's necessary or anything.
Chapter 17
“...she never recognises as gluttony her determination to get what she wants, however troublesome it may be to others.”  Give some examples of this quote.
Now that this is pointed out, I guess I am guilty of this too. I am really a perfectionist, and I want things done "right." But that's just an excuse to say that I want things done my way. So I get so caught up in running things that I don't really care what others think or feel as long as I get it done. This is a major problem that hasn't been pointed out to be until now.
“...all I want....”  What are your reactions to this sin?
I think that it's different from the perspective you look at this. If you were that waitress to this woman, then you would think that this girl is a stuck up snob. But, if you were this lady saying this then you think that you're doing this waitress a favor by letting her not make so much. I honestly think we're all guilty of this is some part of our life. This is a very tricky sin that we have to watch out for.
“...insatiable demand for the exact, and almost impossible, palatal pleasures which she imagines she remembers from the past.” Gone are the days “...when her sense were more easily pleased and she had pleasures of other kinds which made her less dependent on those of the table.”  What does this mean?
As a teenager, we do this a lot with relationships; or at least I do. I think that a relationship was so much better in the past, but its just me getting "dull" to a person over time. This is actually hard to explain, but I hope you know where I'm going with this.
Chapter 18
Why would God want “complete abstinence or unmitigated monogamy” for us?  
God wants this because there are so many problems if you are not in complete abstinence or unmitigated monogamy. There's the consequences of maybe having a baby that you're not ready for. So you either struggle through life or worse case is that the baby get's aborted. Also, another problem is that people get deseases because they are not staying pure. If we listen to God's plan for us then it's a much easier rode.
Define “being in love.”
To me, being in love mean to have five girlfriends and each one holding one book for classes during school. Just joking! To me, love is being able to see a girl for who she truly is and really "loving" her for that. I would say a long list of what love is but then I would just be copying 1 Corinthians 13.
