Yeah, I realized that afterward (but too late to edit the post), but never got around to posting a correction. I had been thinking of the form altar, -āris, but even then it’s neuter and the accusative would be altar. You’re right about the ecclesiastical form, altāre, -is.N.B., altare is neuter, so it is the form both of the nominative and accusative cases in the singular, e.g., Introibo ad altare Dei. Altarem is not a Latin word.
Note to self: do not correct people unless you’re really sure you’re right.
