unfortunately, you are not allowed to attend mass this sunday. Indoc is officially over after change of command (when control of the candidates go from the drill instructors/OICs to their CTO and prospective company's chain of command). they will not be getting any liberty this weekend, nor will they until parents weekend. once indoc is done with, you are allowed to attend mass on sundays and stay for at least an hour, however, i wouldn't bring food for the whole platoon- your p/c will have a group of kids that he'll want to bring to land hall with him (where the parents usually go after mass)
