As Mike says, you don’t have a choice whether to believe or not.
If I give you some evidence about anything - the existence of aliens, unicorns, gods…whatever, you will either consider the evidence to be reasonable or not. So you will either accept it or reject it to a certain extent. That then defines your belief about the matter.
It is impossible to believe something if you have rejected evidence about it and equally impossible to disbelieve something if you accept the evidence.
It is not impossible. It is not even hard. There are many cases when evidence is not overwhelming and one can easily make a choice.
For example, neither evidence for P=NP nor evidence against P=NP is overwhelming. Yet I believe that P=NP. Why? Simply because I think I am more likely to discover a good algorithm solving NP-complete problems than a proof that P!=NP. And looking for an algorithm while believing it is not there to be found is harder (it is harder to motivate oneself). Naturally, I am not going to lose much if I’m wrong - I can just change my mind.
Another example is that doctors who have an ambiguous diagnosis act as if they believed that the patient is sick. Once again, not because of evidence (it is, um, ambiguous), but because of different risks.
As we can see, we use such reasoning all the time. Why do atheists act as if there is suddenly something wrong with applying the same reasoning to religious matters?
In fact, it is only hard when one tries to believe against evidence (although I’m pretty sure any of us can find someone who did manage that “feat”). But no one on this thread has claimed that evidence against existence of God is anywhere close to being overwhelming.
I have problem with E. How could you justify that?
In fact, E can be softened: it is enough that not believing in God makes going to Heaven harder or less likely. In that case it is pretty obvious that guessing right makes it easier to act as one should.
For example, going to Mass and receiving sacraments makes going to Heaven easier. But you won’t do that without at least an “imperfect faith”.
And also their demerits: “If I believe in the Christian God, and I am wrong, then Allah will smite me.” You need to consider the downside of any choice as well as the up side.
Actually, it is at least arguable that Christians and Muslims worship the same God. And even if Muslims are right, being a Catholic is a much better option than being an atheist. In fact, the same is true for many other religions - the only alternative is that one doesn’t lose much. For example, if Mormons are right, one can still be baptised after death - not that much of a loss. Or, if Buddhists or Hinduists are right, one can still try again after reincarnation - also not that much of a loss.
And, of course, as PRmerger has just mentioned, evidence for Catholicism is much stronger than evidence for some random paganism.
- What benefit would come if I, someone who doesn’t believe there is enough evidence of the Catholic god, get from praying or going to church other than going through motions? Giving to the poor I already do. That can be done independently of being a Christian.
If imperfect contrition (being sorry for one’s sins just because of fear of Hell or something similar) is sufficient with sacramental confession (see, let’s say,
catholic.com/encyclopedia/attrition-or-imperfect-contrition), why should we be so sure that “imperfect faith” won’t be sufficient with sacraments and the like?
