A comparison between (GFT), Møller's tetrad theory of gravitation (MTT), and general relativity is carried out regarding the Lagrangian of each theory. The results of solutions of the field equations, of each theory, are compared in case of spherical symmetry. The differences between the results are discussed and interpreted.eleven pages latex file, the authors list is shortenedGeneral Relativity and Quantum Cosmologytext
