Is this a trigger for you? That seems to be a pretty strong response considering many of the other much more difficult things in the Bible. There are still verses like Psalm 14:1 or 53:1 as well:
"The fool says in his heart, “There is no God.”
Many Christians would probably merge all those together along with Psalm 19:1: “A psalm of David. The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they display knowledge. There is no speech or language where their voice is not heard.”
That is how they read Romans 1:20: 20 For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
I suppose one could take verse 21 as applying to believers only as you seem to do and atheism wasn’t all that common back then so maybe it has some merit. Plus those Psalms are also not really addressing philosophical atheism (at least directly) at all but talking about people who live like there is no God, who live like God is not concerned with human affairs, and they then live greedily and harm others to get ahead without worry. I think that is more the intent of the Psalms but I am not sure they would be open to philosophical atheism either. I doubt Paul would have followed your distinction or thought highly of or made special caveats for intellectual atheists.
Many Christians see atheism not as some simple neutral choice but as a rejection of God. Clearly these atheists today have heard the Gospel message in some form and have access to God, Scripture and His creation which show his eternal nature and divine qualities. The Christian then sprinkles in some Jesus from John 3:
16For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. 17For God did not send his Son into the world to condemn the world, but to save the world through him. 18Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son. 19This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil. 20Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed. 21But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God.
This leads to the notion that the nonbeliever rejects God and his Son and per Jesus’s own words, he will reject them before the Father. There are a lot of other moving parts in this belief besides just what we see in Romans 1 and 2. I think the issue is a bit more complicated and I think sin and a spiritual component don’t make it easier.
It might not be tactful in a debate to tell someone they don’t believe in God because their wickedness suppresses the truth but is there something wrong with being a Christians and believing what the Bible plainly narrates? Do you not think there is some spiritual component related to belief/unbelief? A reformed theologian would say those of us believe only because God elected us to no? We are all evil and unable to believe. But even for non-reformed theology, faith is certainly not a purely intellectual endeavor in my book. It seems to me that the Bible speaks regularly of hard hearts, people being given away and wickedness suppressing the truth and obscuring the light and so on. I think this is a very complicated issue though. Because it immediately raises issues of election and why some believe and some don’t. I don’t consider myself good or better than atheists because I know God. I consider myself worse. Having seen the light and goodness of God and still sinning? Woo boy! Let the Catholic guilt flow! I consider myself lucky and blessed and wish the same for everyone. If I truly believe I was saved by God’s grace, how can I look down on anyone else? All I can do is be thankful for what I have.
It might be frowned upon but the Bible does clearly speak of hard hearts and wickedness suppressing the truth. But this occurs in believers and non-believers. If we want to take our faith seriously we have to contend with the fact that sin and spiritual forces are at work in the world. Evil definitely dims the light of spiritual truth. The Bible seems to indicate nature plainly reveals God’s glory. This does not leave atheism in a good light. I see a lot of excuses for atheism in this thread. I had to check to make sure I was on a Christian website and not the Secular web. As a Christian I cannot view “rejecting God’s offer of grace and salvation” as good or neutral thing. Of course I understand shades of gray and subscribe to wider-hope theories and realize the Bible nowhere specifically addresses modern philosophical atheism but I don’t see it as some great bastion of free thinking. Is it merely lacking belief or an outright denial of the Truth and Light they have been exposed to? Tough questions. But I find it undeniable that following God would mean making changes a lot of people don’t want in their lives so they do their best impersonation of Jonah.
“To be happy"sounds more like modern, talk-show pop-philosophy to me than a well-reasoned, examination of life. I’d be much happier if I could legally carry my firearm to work with me. I m not so sure that is the same as spiritual joy though or that it is going to lead me to the most fulfilling and rewarding existence possible. Reliance on God is what is supposed to do that for the Christian. I suspect a lot of Christians would associate true happiness with being closer to God and while not completely shunning world happiness, recognize some sort of distinction between them. For many Christians it is unfathomable that a person could be truly happy without God. Though it seems like some believers are quite miserable themselves at times. In the end there is a spectrum. None of us accepts or rejects God in a vacuum and for me, to live a fulfilling and meaningful life under the golden rule is at least significantly how God intends us to, whether atheist or Christian. I think people can glimpse and follow the Divine in many forms. You don’t need to know the name of a road to travel down it. God is greater and bigger than any religion but " living the life they way they want to live” is most certainly un-Christian. We profess to follow a power higher than ourselves and follow His will. That is the only tally that ultimately matters.
