Here are what I think are some primary, secondary, and tertiary theological issues:
PRIMARY:
- Trinity
- Substitutionary atonement
- Hypostatic union
- Christ’s resurrection
- Christ’s second-coming
- Inerrancy of Scripture
- Virgin birth
SECONDARY:
- Calvinism/Arminianism (due to its effect on your view of God and Scripture)
- Cessationism/charismaticism
- Women in ministry
- Baptism
- Lord’s Supper
TERTIARY:
- Credo/paedo baptism
- Earth age
- Eschatology (as in pre/post/amillenial, dispensational, etc.)
- Church polity

Would anyone erase a third tier altogether?
Would anyone add or move something to a different category?
Would we agree that anyone who denies primary issues would be heretical?
