Mariano Rivera and his wife, Clara, allegedly covered up child sexual abuse that took place at their home and at one of their church's summer camps ... this according to a new lawsuit, obtained by TMZ Sports.
The bombshell allegations were spelled out in court documents that were filed this month in New York -- and while neither Rivera nor his spouse are defendants in the suit ... they're both named repeatedly in the papers.
Mother A Doe alleges in the docs her daughter, a teenager ID'ed only as Jane A Doe, was convinced by Clara in 2018 to travel down to Florida for an internship that her Refuge of Hope Church was helping put on.
