I was having a discussion with someone about Pascal’s Wager, as well as St. Thonams’ Aquainis’ Ways and the point was brought up about how we can’t possibly know that God is the Christian or Abrahamic God. I know this has probably been addressed on here in the past, but I couldn’t find it in the search. What proofs are there that God is the Abrahamic God? I know it can’t fully be proven, because we need to have faith, but what is a rebuttal we can possibly have? How can we assure ourselves that the God that Aquainis lays down proofs for is the Abrahamic God? Thank you.
This is among the most relevant questions ever posted on CAF, despite the poor grammar.
The answer is simple: You cannot.
Aquinas and ongoing theologists do not address the properties of God, perhaps assuming that the Catholic/Christian definition of God as an omnipotent, omnipotent, omnipresent spiritual being is absolutely correct.
The reality is that this definition, devised IMO as an exercise in theological one-upmanship, is inherently illogical. I’ve pointed out elements of this elsewhere-- for example, if God is omniscient, He cannot think. If God is all-powerful, He cannot utilize that power without destroying the universe.
Were Christian theologists to take their work in a spirit similar to that of scientists, they would re-investigate their definition of God in the context of current information. That won’t happen, and you will not get your answers.
Rather than seek the answer to your question in a place where it does not exist, why not investigate the question yourself? Ask yourself what are the minimal properties that an entity requires in order to create the universe?
Physics can help you out here. The First Law of Thermodynamics, for example, informs you that the stuff of the universe, energy, cannot be created (or destroyed). Therefore, you do not need to invent a God who can create the universe from nothing, but rather from a raw material readily at hand.
Keep that agnostic friend handy and try kicking around ideas with him instead of against him.
