Akin's Tiptoe Through the TULIP (a response)

The recent challenge is over what Jimmy Akin has posted as
a Catholic or Thomist view of John Calvin's TULIP. Since this
is the case, I will now respond to Akin's article:

> A Tiptoe Through TULIP
> by James Akin

Akin's words will be preceded by ">" and mine will not be.
Jimmy's original article can be found here:
http://www.cin.org/users/james/files/tulip.htm

This response of mine can also be found in the
Catholic Debate Forum (click here).

I would beg to differ here. Calvinism does not have the
"enormous influence" which Akin attributes to them. They
ARE a minority. What they DO have an influence over is in
the apologetics community - for they tend to be among the
most vocal/verbose and as such many Catholic apologists
put an undo amount of focus in responding to them and I
am guilty of this too, largely due to the influence I put
myself into after I converted to the Catholic Faith. Prior to
my conversion I had scarcely even heard of John Calvin and
Calvinists - my upbringing was Lutheran, which is definitely
NOT Calvinist.

The only point I would add here is that God is outside of what
WE consider to be "time." God is eternal. God always was,
is, and will be. What WE perceive as "future" - God just sees
for God just IS. He is I AM.

I would add: Many Calvinist arguments against Catholics are
based in #2 - where they are responding to Catholics who do
not understand the Catholic stance on predestination.

True Calvinists would not say we "choose" anything of our
own Free Will.

Or, we can base our opinion on Scripture:
Isa 64:6 But we are all as an unclean thing, and all our
righteousnesses are as filthy rags; and we all do fade as
a leaf; and our iniquities, like the wind, have taken us away.

Amen.

In short, in Calvinism men are puppets. Calvinists
don't like to hear this, but that's the reality. In their
invented system, if God chooses you - you have no
real choice, you WILL choose to follow God, period.
If God DOESN'T choose you - then you are lost,
damned to Hell for all eternity.

Speaking for myself, I have long considered myself to
be a Thomist - but I do not agree with unconditional
election.

With all due respect to St. Augustine, Scripture tells
us that ALL are drawn! John 12:32 states that when
Jesus is lifted up, He will draw "all men" to Him.

Or the wiser approach might be to not try to figure out the
Mind of God so much. A couple facts are clear, man
stands condemned by Original Sin. Without the grace of
God, NO man can be saved. Then when we couple these
facts with the statement from John 12:32 - we know that
"all men" are drawn - thus those who do NOT come to
Him are the ones who failed. God has not failed to
redeem the world. My position is also confirmed in what
Mr. Akin quotes from the Council of Trent:

> The Council of Trent stated, "If anyone says that it is

And as I referred to earlier, John 12:32 states that when
Jesus is lifted up, He will draw ALL MEN to Him. The
case for limited atonement is just non-existent.

Amen.

While I agree with the essence of what Akin says here,
I do not feel the need to be drawn into accepting the
terms of Calvinism at all. God is not limited, period.

Can anyone tell me how the "I" is really any different
from the "U" in TULIP? Both speak to the inability of
man to play any role in the economy of salvation.
They are both statements of predestination. It seems
to me someone just wanted to make sure all the letters
in the acronym were used! With unconditional election
you're either of the elect - or not. With irresistible
grace, if you're given the grace you can't refuse it, but
if you're not given the grace, there's no way to get it.
Both the U and the I pretty much destroy the TRUE
Gospel we are given in Scripture.

Or if you're a Sci-Fi fan, like the Borg saying, "Resistance

But then it would be "TULEP" and that just doesn't work! (grin)

Well, I would say ALL grace from God is efficacious, but not
all will choose to RECEIVE that grace. There is no grace
from God which would NOT be efficacious, it is rather silly
to consider such, in my humble opinion.

And I might add, perhaps the best example against the
doctrine of perseverance of saints is the story of the
Prodigal Son (Luke 15:11-32). The Prodigal was
considered to be "dead" by the father, but upon his
return the father considered him alive again.

The argument is based in the presupposition that the
Calvinist view of predestination in the first place is
correct - which it is not.

Well, I would not even give them these two types of
salvation. Salvation is the prize, in the words of St.
Paul, at the end of the race.

Again, this whole concept of "initial salvation" I would not
agree to. I would call that "initial grace" or "initial
justification" but not "salvation."

Amen.

I like St. Thomas' approach!

Agreed.

Or, as St. Thomas said, those who have received the
gift of perseverance.

That is well and good, but the criticism of using their terminology
still exists (as with my initial article which did much the same as
Akin's here does). If one is to convert to the True Church, then
why hang on to errors of the past at all? When one converts, they
need to RENOUNCE their past - and EMBRACE that which they
now KNOW to be the Truth. Let's not "tiptoe through TULIP," let's
just crush the TULIP so they can move on and know the Truth.

  1. I also want to make it clear, I am not in disagreement with Jimmy Akin's presentation. I am not in favor of taking an anti-Catholic acronym and making it "Catholic" (though I did the same thing with TULIP years ago, and can't find my rendition of it now) as that may lead to confusion by the readership. One sitting on the fence may feel, "If I don't have to give up TULIP, then why should I become a Catholic?" Yes, a weak argument to be sure - but we're not talking about one firmly rooted in the Faith.

    In short, to present a "Catholic TULIP" may seem like a false ecumenism. I know it is not. I know it is an attempt to convert the falseness of Calvinism to the truth of Catholicism - but is that really necessary?

    I invite others to post their comments here as well. I'd especially like to hear from Jimmy! I'm dropping him a message too, I don't know that I did previously as I would appreciate his take on my response too.

  2. We're going on two years without additional comments here! I just want to emphasize that while it is interesting to come up with a "Catholic TULIP" or a "Thomist TULIP" - I see a real danger in using such terminology. It may encourage a Calvinist to become complacent... "If I don't have to give up my TULIP, why even convert?" Of course the answer to that is quite obvious because Calvinism and Catholicism are not mutually acceptable at all, but if someone is looking for an excuse, the use of such terminology may crush the conversion at the bulb.

  4. Jeph writes: FYI, "men" in John 12:32 does not appear in Greek.

    The Strong's Concordance would agree with you here - however context would dictate that the "all" here refers to "all men." After all, we're not thinking He refers to all goats or all ants, but the subject. Another way to look at this is going back to verse 31 - where the context is the judgment of this world - and going back a few more verses to 26 He says "if any man serve Me, let him follow Me."

    Now there is room in this passage to say Jesus was referring to all types of men - but you would have to read John 12:32 in a vacuum, apart from the context of the rest of Scripture - even John himself in chapter 3, verse 16 where it is recorded that God so loved the world (not just a part of it) that whosoever (not just a select few) believes in Him shall not perish, but have everlasting life.

    So, in context, John 12:32 is referring to "all men" - even if the word "men" is not in the Greek.

  5. The context of John 6 dictates that the drawing referred to (in John 6) is exclusive. Read the whole chapter, especially verses 63-65.

    Christ explained that the reason why only some believe him is that NOBODY CAN COME to the Father unless they were drawn. COnsequently, the reason why others do not believe is that they were NOT drawn.

    At this point I should appeal to the unity of Scripture in its divine teachings. It cannot contradict itself, so your interpretation on John 12 is automatically incorrect.

    Good day and God bless!@

  6. Hi Jeph,
    I assure you I've read through the entire chapter of John 6 numerous times, and it is not I who is reading this wrong. Please note it says "no man CAN (emphasis mine) come to the Father unless he is drawn." That means once there is a drawing it is POSSIBLE to come to the Father. Thus, in John 12:32 where ALL are drawn to Him, that drawing of ALL does not mean that ALL will heed the calling/drawing. For many are called, but few are chosen (Matt 22:14). This is a clear statement that the number called (or drawn) is larger than the number actually chosen (or who come).

    There is no contradiction in the Catholic understanding of John 6 compared to John 12.

    I may reblog on this soon - since the post you're responding to is more than 2 weeks old, all comments require a moderator to approve before they are published - so until I do reblog, please pardon any delays in your comments being posted. Since the topic you're discussing is somewhat tangential to "Akin's Tiptoe..." I may just compose a new blog on John 6 and 12 and direct your comments there.

  7. Jeph, to get you started - earlier this year (2010) I posted the following article on John 6 as being primarily a Eucharistic treatise:

    http://cathapol.blogspot.com/2010/02/john-6-and-james-white.html

    The person I was responding to is (or was anyway) a huge James White fan, so some of the focus is spent responding to White's Fatal Flaw (White's first book on Catholicism which he wrote after and primarily based upon debates he had with me, a new convert at the time).

  8. "At this point I should appeal to the unity of Scripture in its divine teachings. It cannot contradict itself, so your interpretation on John 12 is automatically incorrect."

    Ironic considering all the other scripture referenced in this blog that supports the author's position that the above quoted critic chose to ignore.

    Anyway, THANK YOU for writing this. I always enjoy seeing more and more examples of just how Biblical Catholicism really is. Of course, for us Catholics, that seems excruciatingly obvious. However, for those who aren't, these examples are necessary. It is sadly ironic, though, that those who scream Sola Scriptura from the rooftops promote theology that must, by necessity, reject some scripture. :(

I have no control over which messages get caught in the spam filter and those that do must wait for me to mark them as "not spam." A message caught by the spam filter may show up for a moment, making you think it posted, and then disappear. Do not assume I have deleted your comment, it's probably just the spam filter and it will show up.
