Romans 15:20

15:20 And in this way I desire to preach where Christ has not been named, so as not to build on another person’s foundation,

Romans 14:4

14:4 Who are you to pass judgment on another’s servant? Before his own master he stands or falls. And he will stand, for the Lord ¹  is able to make him stand.

¹ tc Most mss, especially Western and Byzantine (D F G 048 33 1739 1881 Ï latt), read θεός (qeos, “God”) in place of κύριος (kurios, “Lord”) here. However, κύριος is found in many of the most important mss (Ì⁴⁶ א A B C P Ψ pc co), and θεός looks to be an assimilation to θεός in v. 3.
