In its most literal sense, I'd agree with this statement, but I know what you're trying to get at, and I have to respectfully disagree here.

Science shouldn't be characterized as a religion. First of all, I feel it is a great insult to religion to do something like that.
I know what the point you're trying to make here is something like: 'science and religion both rest essentially on metaphysical axioms which can't be distinguished from each other' and I agree to a point (though I do think we can distinguish, just perhaps not rationally or in a value neutral way).
However, going beyond that, I'd add these major differences between the two. Religion really has to have ritual tied to it. I think ritual is a necessary condition, otherwise I would say something was 'philosophy' (for lack of a better term). And I really don't think something like research programs could be counted as ritual.
Furthermore, religion and science are even more distinguished today due to the secularization of science. Lindberg, Grant, and Hannam in their histories of science do an excellent job of showing how premodern science was very closely tied with religion and ideas of the supernatural. However, methodological naturalism now is the de facto methodology and actual metaphysical naturalism is assumed quite often. This to the extent that you will have people nowadays argue that science as we know it did not exist until 400-500 years ago, or even later than that (and if you accept their definition of science, they have a point).
Also, the domains of science and religion are different. I definitely don't agree with people who say they do not intersect as there is some overlap, but despite that, science (nowadays) is almost wholly exoteric in focus. Religion is both exoteric and esoteric, and the latter plays a big part in its identification.
