Secularism and atheism both reject theism’s ingratitude problem by privatizing God

Evidence

Obviously, secularism and atheism are not interchangeable categories, but the secularist relegation of God and religion to the private domain makes both the secularist and the atheist, insofar as the problem of ingratitude is concerned, equally antithetical to theism. — Wael Hallaq, Restating Orientalism, 989

Categorization

• QUESTION: What exactly is the ‘problem of ingratitude’ here — presumably humans owing God gratitude — and how central is it to the argument?
• XREF: connects to: Sartre’s atheism rejects specifically the Scholastic creator-God.
