Let \(R\) be a noetherian commutative ring and \(\mathrm{mod}(R)\) the category of finitely generated left \(R\)-modules. After the introduction of Gorenstein homological algebra, the study and classification of resolving and thick subcategories of \(R\)-modules become a fundamental problem. In this paper, it is shown that there exists a bijection between the collection of resolving subcategories for a thick subcategory containing \(C\) and consisting of totally \(C\)-reflexive modules, where \(C\) is a semidualizing module, and the set of grade consistent functions as used by \textit{H. Dao} and \textit{R. Takahashi} [Int. Math. Res. Not. 2015, No. 1, 119--149 (2015; Zbl 1314.13024)]. When \(R\) is Cohen-Macaulay with dualizing module, the preceding result yields a bijection between resolving subcategories of maximal Cohen-Macaulay modules and grade consistent functions. In the last section, local Gorenstein rings are considered and several interesting bijections are obtained as well.
