Explanation

This harmony differs from many of the others in that it begins with the Confession which recognizes its natural pedagogical and chronological priority over the Catechism and the Canons. Confession is the product of the work of the
departments of theology (exegesis, dogmatics, historical & practical theology). In turn, catechesis is the product of
confession.

The Canons are a clarification of the Reformed soteriology inherent to the Catechism and the Confession. The canons
however, have a special place in that they address only two loci of theology and are not therefore a comprehensive confession and thus they are correlated to the two earlier documents which the Synod ratified and adopted.
