The First Amendment prohibits Congress from establishing a religion (or disestablishing one). How can Congress pass such a law, when marriage is a sacrament or religious ritual?
You don’t even have to “reach” that far...marriage is not an enumerated right, thus Feds cannot constitutionally have jurisdiction over this issue. The bill will be utterly unenforceable.

There are a lot of civically ignorant, or outright indifferent people in this country, and many of them vote.
On a different note, I support the idea of a Convention of States, and would love to see an uncorrupted convention happen in my lifetime; but, considering the reaction of some states to the Bruin decision earlier this year, both Lindsey Graham and Joe Biden talking about federally codifying Roe after the Dobbs decision, and finally this travesty that just passed I do not believe that Congress would honor anything to come of that convention.
