Reddit mentions of Aquinas's Shorter Summa: Saint Thomas's Own Concise Version of His Summa Theologica

God bless you! :) I love how you have shared your testimony.

I'm a young Christian guy and, unfortunately, struggle with porn and masturbation as well. So I do relate to your troubles there.

As someone who is new to the Christian faith, you might find this book REALLY helpful:

https://www.amazon.com/Mere-Christianity-C-S-Lewis/dp/0060652926/ref=sr_1_1?ie=UTF8&qid=1473987989&sr=8-1&keywords=mere+christianity

It is called "Mere Christianity" by C.S Lewis, who, fun fact, is also the auther of the "Chronicals of Narnia" fiction series.

C.S Lewis was a devout Christian and has wrote many great books on the Christian faith. I would also reccomend his book "the Screwtape Letters" which is a book about demons. And it might help you with temptation, as you shall realise the spiritual reality of what happens whan you go through that tempation.

You also mentioned that your parents are Catholic, so they might appreciate that you learn Theology from the renowned Theologian,

Thomas Aquinas: https://www.amazon.com/Thomas-Aquinas-Selected-Writings-Classics/dp/0140436324/ref=sr_1_1?s=books&ie=UTF8&qid=1473988742&sr=1-1&keywords=thomas+aquinas

Thomos Aquinas is not only one of the greatest philosophers of Christianity, but one of the greatest philosophers PERIOD.

Just by reading, you can really learn a lot about the nature of God, what it means to

pray, how to properly interpret Scripture, understanding your

sexuality, the proper use of meditation etc.

Just reading one book can inform you a LOT.

I say this because, a lot of times, new Christians ask how or where

they can learn more about Christianity. Which is funny because the

answer is right in front of them. :) You learn more about religion

just as you learn more about everything else iln life. Through books.

)

Anyways. God bless you in your newfound relationship with Him.
May you grow in faith and find righteous abstinence from sin.
Pray for me as I shall pray for you.

Deo Gratias! +++

To add to this, if you want proof that God exists, Thomas Aquinas is your guy. [This book] (https://www.amazon.com/gp/aw/d/1928832431/ref=mp_s_a_1_1?ie=UTF8&qid=1502744241&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=Aquinas%27s+Shorter+Summa%3A+Saint+Thomas%27s+Own+Concise+Version+of+His+Summa+Theologica&dpPl=1&dpID=415GX3S4CFL&ref=plSrch) gives tons of logical arguments about the existence of God. I'll warn you - it's a heavy read, but if you approach it with some time and persistence, it's worth it. Check out your local library for it. Aquinas is my guy for all logical arguments.

Oh man. Where do I begin?

It started with Edward Feser. Then Aquinas.

I recently compiled my 'short list' of books that were foundational for a Master's:

Start here:

https://www.amazon.com/gp/product/019925995X/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Then go here:

https://www.amazon.com/Story-Christianity-Vol-Church-Reformation/dp/006185588X

https://www.amazon.com/gp/product/0061855898/ref=pd_sbs_14_t_0?ie=UTF8&psc=1&refRID=T5D86TV1MTCSQAYZ4GHR

G.K. Chesterton is always a good supplement (Heretics and Orthodoxy):

Bible Study:

https://www.amazon.com/Introduction-Testament-Anchor-Reference-Library/dp/0385247672/ref=sr_1_1?s=books&ie=UTF8&qid=1477868333&sr=1-1&keywords=raymond+brown

https://www.amazon.com/gp/product/0809147807/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

(Jewish perspective on NT): https://www.amazon.com/gp/product/0195297709/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

After you've gotten through these (or maybe interspersed), get into de Chardin -- but be careful, because he toes the line into heresy with the noosphere stuff.

Then, start reading the theoretical physicist priests in our faith, Stanley Jaki, for example.

And this. This.

Finally, try to muddle through Spitzer. These guys have more smarts in their little finger than I will ever have.

Edit: I refreshed the thread and saw that you've already found Feser. Excellent. Are you familiar with John C. Wright as well? Sci-fi-writer-former-atheist-now-traditionalist-Catholic.

I'm interested in any science + metaphysics books you've come across too. . .

As others have mentioned, the Nicene Creed is the most basic summary of the faith. I highly suggest picking up a copy of "Catholicism and Reason: Creed and Apologetics." Its a very easy read and takes you step by step and line by line with the Creed.

The book above is a great starter but for something with a little more material, you would probably want to go for Thomas Aquinas' Summa of the Summa Theologica also called "The Shorter Summa."
https://www.amazon.com/dp/1928832431/ref=cm_sw_r_cp_awd_Qow4wbNBB8V3B

You can also never go wrong with anything by C.S. Lewis or Scott Hahn. I hope this helps!

An updated version of Kreeft and Tacelli's book (and extra couple chapters for Catholics): Handbook of Catholic Apologetics

Edit: I also wish to plug my own favorite, Aquinas' own shorter, yet unfinished, version of the Summa Theologica.

Here are some books I recommend. Some are free on kindle. Check out a library. They will have these books.

Read the 4 Gospels and Acts of the Apostles. Just read them.
