John 12:48-50

New Revised Standard Version, Anglicised Catholic Edition

⁴⁸ The one who rejects me and does not receive my word has a judge; on the last day the word that I have spoken will serve as judge, ⁴⁹ for I have not spoken on my own, but the Father who sent me has himself given me a commandment about what to say and what to speak. ⁵⁰ And I know that his commandment is eternal life. What I speak, therefore, I speak just as the Father has told me.’
