Do you have an obligation to attend mass on Sunday? :nope:
But Catholics do (or should). So, again, there are many things that believers may do or not do specifically because they believe those things to be commanded or prohibited by God.
You are again assuming that what Catholics believe they should do applies to anyone who might believe in God.
And how would you even know what the right thing to do is apart from an objective moral standard?
Whether I have a deeper understanding of morality than you is uncertain. I don’t always understand things as well as I should. What I do have is a better foundation for morality than you, because the basis for my morality is God.
I get this comment thrown at me more times than I could count. And the problem is always that it is not used as the basis for a discussion, it is used as an exclamation mark to stop any discussion dead in its tracks.
‘My basis for morality is God, therefore any comment you make on the matter is worthless’.
Usually with a facile comment about preferences thrown in. As if an atheist’s position on any moral matter is just a whim.
So let’s unpack a moral problem and see where we go with it.
First up, I consider human life and dignity to be important. This stems from a naturally evolved empathy and reciprocal altruism aka the Golden Rule. Every moral code that has ever existed has this at its heart, whether religious or not. Matthew 7:12 is your version, but there are plenty of others. If you want to say that God has placed this in our hearts so that it is divinely ordained, then take some time out to discuss why almost all sentient creatures have it and tell me why God needs bats to be morally accountable:

So harming someone without a very good reason or treating them in an undignified manner is wrong. Everyone (except psycopaths) understands this whether they have a religion or not or whether they believe in any god or not. Now if you want to cut and paste this paragraph out and then bang out the quote above ('My basis for morality etc), then please save yourself some time. It changes nothing.
I’ve been explaining how my suddenly believing in God would not make me a better person. Now it’s your turn to assume the reverse. If you woke tomorrow NOT believing in God, would you then think that harming someone for no good reason or treating them disrespectfully was therefore now perfectly acceptable?
I doubt it very much. So we can agree that they are positions that require no reference to a higher power and which we can use to determine whether a moral act is right or wrong.
Now I will bet my house on the fact that you could easily put forward an argument against honour killings without mentioning any divine impremanteur. Just using empathy and reciprocal altruism as the basis and using the universally agreed maxim ‘cause no harm’.
Once done, how would you respond to me, rather fatuously, suggesting: ’ Well, Randy, that’s just your opinion’. Just an opinion? Like a preference maybe? Or a whim? A position you took with no real thought? A statement that carries no substance? An inconsequential argument that could have gone either way?
The fact is, we would both, as Christian and atheist, come to the same conclusions using the same arguments and we would both feel justified in preventing someone from causing harm in the manner described. If we both woke up tommorow, me believing and you not, the arguments would still be the same and they would carry as much weight as they did the day before.
The fact that either of us could say ‘Hey, today I appear to have a basis for my morality’ is completely, totally and undeniably irrelevant. We would both, whichever position we held in regard to a belief in God, be entirely justified in claiming that our position was the morally correct one.
