Of course. An even sharper example is the fourtieth of the 40 Martyrs of Sebaste, the Roman soldier, who wasn't even a catechumen, but declared his faith in Christ upon seeing the thirty-nine remaining on the ice, and went out to take the place of the apostate.
Ah yes I had forgotten that story, excellent example!
And I would also say this...and I am pretty sure you will agree. That notwithstanding Emerentiana's and the soldier's not having received Baptism, they were nevertheless saved *in* the Church and *through* the Church. They just gained their membership in a different way. So we can still confidently and boldly hold to the maxim: "outside the Church there is no salvation".
