Paralambanō (G3880) means to receive alongside, to take along, or to accept what has been passed on. It is the technical term in Paul for receiving apostolic tradition (paradosis) — 1 Corinthians 15:3 uses it for the kerygmatic tradition Paul himself received and passed on.
The phrase 'I received (parelabon) and passed on what I also received' (1 Corinthians 15:3; 11:23) marks the chain of apostolic tradition — the gospel itself is not invented but received and transmitted. This word safeguards the historical, handed-down character of the faith. Colossians 2:6 applies the same concept to the reception of Christ: 'As you received (parelabete) Christ Jesus as Lord, continue to live your lives in him.'
