Some perspective:
DOCTRINE. A theological formulation that attempts to provide a summary statement of the teaching of Scripture on a particular theological topic. Ideally, doctrine is formed by attempting to be faithful to Scripture while giving attention to the traditions of the church and the thought patterns of the day. Thus doctrine is stated in such a way that contemporary people can understand the teaching of the ancient Scriptures.

DOCTRINE. In the Old Testament the word occurs chiefly as a translation of
leqaḥ, meaning ‘what is received’ (Dt. 32:2; Jb. 11:4; Pr. 4:2; Is. 29:24). The idea of a body of revealed teaching is chiefly expressed by
tôrâ, which occurs 216 times and is rendered as ‘law’.
In the New Testament two words are used.
didaskalia means both the act and the content of teaching. It is used of the Pharisees’ teaching (Mt. 15:9; Mk. 7:7). Apart from one instance in Colossians and one in Ephesians, it is otherwise confined to the Pastoral Epistles (and seems to refer often to some body of teaching used as a standard of orthodoxy).
didachē is used in more parts of the New Testament. It too can mean either the act or the content of teaching. It occurs of the teaching of Jesus (Mt. 7:28,
etc.) which he claimed to be divine (Jn. 7:16–17). After Pentecost Christian doctrine began to be formulated (Acts 2:42) as the instruction given to those who had responded to the
kērygma (Rom. 6:17). There were some in the church whose official function was to teach this to new converts (
e.g. 1 Cor. 12:28–29). For the content of the
didachē, see E. G. Selwyn,
The First Epistle of St Peter, 1946, Essay II.

The New Catholic Encyclopedia states:
"The word doctrine comes from the Latin doctrina, the Vulgate translation for didaskalàa and didacø. It means teaching or instruction and is closely associated with the words 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.
Concerning the system of Christian doctrine, early summaries and creeds soon coalesced into the present form of the creed, where there is expressed: first, belief in God the Father of all; then belief in Christ the Redeemer, involving an account of salvation history especially as seen in the mysteries of His Passion, death, Resurrection, and Ascension; and finally, belief in the Holy Spirit and His work of sanctification in the Church, which will continue until the end of the world."
I would say that scripture is doctrine.
