John Chrysostom, on Heb 13:15

“By him therefore let us offer the sacrifice of praise always to God, that is to say, the fruit of lips confessing to his name.”

“And "by Him let us offer a sacrifice to God." Of what kind of sacrifice does he speak? "The fruit of lips giving thanks to His Name." They, the Jews, brought sheep, and calves, and gave them to the Priest: let "us" bring none of these things, but thanksgiving. This "fruit" let "our lips" put forth. "For with such sacrifices God is well pleased." Let us give such a sacrifice to Him, that He may offer it to The Father. For in no other way it is offered except through the Son, or rather also through a contrite mind. All these things are said for the weak. For that the thanks belong to the Son is evident: since otherwise, how is the honor equal? "That all men" (He says) "should honor the Son even as they honor the Father." (John v. 23.) Wherein is the honor equal? "The fruit of our lips giving thanks to His Name."”
