The absence of parables in the epistles and in the book of Acts is a strong argument that those in the Gospels were not inserted by early Christians but were spoken by Jesus himself.
See, et kirjades ja Apostlite tegude raamatus pole ühtki tähendamissõna, on tugev argument selle kohta, et evangeeliumides olevaid tähendamissõnu ei mõelnud välja mitte algkristlased, vaid neid rääkis Jeesus.
