President Joe Biden has asserted that no “mainstream” religion claims to know when human life begins, contradicting his Catholic faith.

Biden made the statement while addressing a leaked draft of a Supreme Court opinion signalling that justices will overturn Roe v. Wade, which legalized abortion nationwide in 1973.

“Roe says what all basic mainstream religions have historically concluded, that the existence of a human life and being is a question,” Biden told reporters at Joint Base Andrews in Maryland. “Is it at the moment of conception? Is it six months? Is it six weeks? Is it quickening, like Aquinas argued?”
