Modern evangelical answers to this question have focused on Christ to the exclusion of these other doctrines but in Reformed theology they’re all connected. Our doctrine of God is intimately connected to our understanding of man, salvation, church, and worship. The Reformed faith, however, is biblical and catholic, i.e., we believe what the Scriptures teach about God, man, Christ, salvation etc as understood by the church in all times and places.

The questions often arise, “what must a Christian believe to be saved”? or “what are the essentials?” Most often the broad evangelical answer is “not much.” The tendency is toward minimalism in doctrine (belief) and practice. In some circles it is enough to say that one came forward at a rally, prayed a prayer, and signed a card (or clicked yes on a website). The Reformed Churches, however, confess a different answer to that question  inHeidelberg Catechism Q/A 22:

22. What then is necessary for a Christian to believe?

All that is promised us in the Gospel, which the articles of our catholic, undoubted Christian faith teach us in sum.

The catechism begins with the Gospel, the Good News about Jesus the Messiah, which is shorthand for his incarnation, death, resurrection, and ascension for us sinners but there is more. The Gospel as we understand it is summarized not just in those events but in “the articles of our catholic, undoubted Christian faith” teach us. The articles to which this answer refers are the 12 articles of the Apostles’ Creed, which are in three sections, organized by the Holy Trinity:

Father:

• I believe in God the Father, almighty, maker of heaven and earth

Son

• And in Jesus Christ, his only begotten Son, our Lord
• Who was conceived by the Holy Spirit , Born of the virgin Mary
• Suffered under Pontius Pilate, crucified, dead and buried; He descended into hell
• The third day He rose from the dead
• He ascended into heaven, and sits at the right hand of God the Father almighty
• Thence He shall come to judge the living and the dead

Holy Spirit

• I believe in the Holy Spirit
• The Holy Catholic Church, The communion of saints
• The forgiveness of sins
• The resurrection of the body
• And the life everlasting.

According to the Reformed understanding all 12 articles are under the heading “gospel.” This doesn’t mean that there isn’t a narrow sense of gospel (as sketched above) but it does mean that when we answer the question of what must be believed we do not stop at the narrow sense of gospel. We include in it the doctrine of the Trinity, a doctrine of God, a doctrine of creation and providence, of sin, of Christ, of salvation, of the church, sacraments, and last things.
