The word doctrine comes from the Latin 'DOCTRINA'. [Ca. encyclopedia, V.4,] It means teaching or instruction and is closely associated with the word 'catechesis' and 'kerygma'. It is used both in the active sense of the imparting of knowledge and in the passive sense of what is taught.
Our Lord Jesus Christ was a teacher,and His teaching was what He had received from the Father [Jn 3.13; 5.17; 8.25-27]. This teaching had continuity whit that of Moses and the Prophets, but it completed and added to it. Our Lord taught with power and authority [Mt 7.29], and man's enternal 'salvation' depended on the way thos teaching was accepted [Lk 9.26]. After Christ's Resurrection and Ascension the 'Apostles' saw their task as that of handing on faithfully what they had received from Christ [Rom 16.17;Gla 1.8; Eph 4.14; Ti 1.9]. The word doctrine was used not only of their teaching [1 Tm. 4.6,16] but of the content of their preaching [Acts 2.42]. It was the good news, the Gospel, and from it stemmed the new way of life of the Christian.
