My Favorite Apologetic Arguments

by Randy Everist

The following two arguments are currently my favorite apologetic arguments for the truth of theism, and by way of subsequent inference to the best explanation, Christianity. I have written about them many times, and enjoy both discussion and answering questions about them. I am going to discuss them both briefly and leave it for your consideration.

The first argument is the kalam cosmological argument (KCA). Cosmological arguments for God’s existence reason from the contingent facts of the universe to a transcendent cause of the universe. The kalam is a particular formulation of this idea. Thus, there is no one singular cosmological argument, only a family of arguments that share the basic foundation in common. There are two versions of the KCA that have been presented by its most prominent defender, William Lane Craig. I will give what I call Craig’s classical presentation, then his current presentation, and then discuss them both. Here is the classical presentation of the KCA:

1. Whatever begins to exist had a cause.

2. The universe began to exist.

3. Therefore, the universe had a cause.

And here is the current presentation:

1*. If the universe began to exist, then the universe had a transcendent cause.

2. The universe began to exist.

3*. Therefore, the universe had a transcendent cause.

The first thing to notice is that (2) appears in both arguments. This is a great premise because it enjoys both philosophical and scientific support…
