While their may be some disagreement, the major doctrines of scripture are as follows;
The Authority and Inspiration of Scripture
The Trinity
The Deity of Christ
Creation by God’s Hand
The Nature of Sin and the Fall
Salvation through Christ Alone ( assuming that includes the death and resurrection of Christ)
Justification by Faith
The Role of the Holy Spirit
Sanctification and Growth
The Return of Christ and Eternal Hope
The above should be agreed upon in order to fall under the belief(s) of Christianity. There are other doctrines that might be considered major and certainly many more that are 'minor' .
