Core Doctrine Class

The goal of this class is to help disciples understand, explain, and apply the core truths of Christianity. Classes will be held from 4-6pm on Sundays, beginning January 14, 2024, and will run for 11 weeks. There will be a cost for textbook/materials. Participation in this class requires approximately 2-3 hours of homework per week—reading and journaling.

Registration is now closed.

Please note: Textbooks will be required for purchase separately from your registration, and are available for purchase in the lobby.

The Purpose Of Core Classes

In an increasingly post-Christian world, the church body needs to know first-hand the sacred text that is the Bible. Core Classes will help you deepen your understanding of Scriptures and doctrine, and how to apply them practically to your everyday life. Core Classes are now a consistent rhythm of our church (offered in Fall and Winter/Spring semesters). Currently, our Core series includes a Scripture class and a Doctrine class.

What is Core Doctrine?

It has been said that theology is for doxology. Therefore the purpose of this class is to increase your capacity to worship! We exist to know God, love God, obey God, and ultimately glorify God. Sound doctrine is an essential ingredient for each of these things. For you cannot love, obey, or glorify what you do not know. Knowledge of God does not guarantee worship of God, but a lack of knowledge guarantees false worship. Our prayer is that you would increase your knowledge of the infinite God so that you can know Him more truly, love Him more deeply, obey Him more fully, and live a life that is glorifying to Him.

What to Expect

Each week, participants will be expected to complete prep-work before attending class—including scripture reading, approximately 20-30 pages of textbook reading, and journaling through some questions about what you read. During each weekly class, there will be discussion of your prep-work within table groups, a teaching on a specific biblical narrative, worship, applicational discussion, and prayer.

Reading, writing in your own words, discussing, hearing and doing, even singing—we all learn in different ways. We’re going to sample all of these learning styles on a weekly basis in the hopes that you will not only retain information, but transform your heart, mind, and practices. 

The content of this class is designed to be challenging to adults. However, we believe it is also accessible to high-school-aged students.

DISCLAIMER: We do ask that you consider whether you are able to commit to a full semester-long class BEFORE you register. We offer Core Classes every Fall and Spring. So, if now is not the best time time for this extra commitment, please consider waiting until a future semester.

Frequently Asked Questions

I'm participating with a spouse—do we each need a textbook?

That will be completely up to you and your specific needs. If you are the type who likes to highlight or make notes/underlines as you read, you may wish to have your own copy.

What if I can't make it to all of the classes?

We understand that you may miss a class or two for various life-and-season reasons. We will do our best to supply you with any notes you may have missed from our lectures. And—we’d highly encourage you to dialog with a friend that week over what you studied, since you will have missed your group discussion time.

That said, if you are looking over your calendar and realize you are likely to miss a fair amount of classes, then maybe this semester isn’t the BEST time for you to take a class. Consider waiting until a future semester when you have a greater likelihood of full participation. You’ll be better for it.

What makes classes different from a small group or bible study?

Classes are primarily an independent, topical study (biblical theology and systematic theology), with the chief purpose of education and increasing your personal discipleship. Classes are for a set period of time (11 weeks), while groups tend to have a more ongoing nature. 

At Gospel City, our small groups have a primary purpose of biblical community—caring for each other, holding each other accountable, and living out the “one another’s” of Scripture. Typically, small groups are not focused on learning outcomes like a class would be.

Classes and groups are not meant to be a substitute for one another, but rather are designed to come alongside one another in a complimentary way. Classes are committed to advancing biblical education, and groups are committed to advancing biblical community.

Why isn't Kids Core being offered this semester?

After a successful beta-run of Kids Core in 2022-2023, we are evaluating ways to enhance it for kids and middle-grade students. We want to offer it again soon with the excellence that you’d expect from us. We are so very thankful to everyone who helped us with the initial run, as well as all of the feedback that was provided.

For now, Kids Core will not be offered during the winter/spring 2024 semester. We apologize for any inconvenience this may cause. However, we plan for Kids Core to return in the fall of 2024 with enhanced middle-grade content (Teens Core). 

Can I take this class with my small group?

While registering, you are able to name up to two other people you’d like to be seated with for discussion and we will do our best to accommodate those requests. However, we believe that Core classes are a great space for you to meet people who are potentially outside of your current circles. We’ve heard many great testimonies of new gospel friendships that were forged by participating in this class and meeting someone new.

Can I take this online/virtually?

Our Core Classes are designed to be taken in-person only.

What if I've already take a Core Class?

We’re thrilled that you’ve already made the commitment to your spiritual maturation. One of the best ways to employ what you’ve learned and further put it into practice is to TEACH it to someone else. Consider taking the class again as a table facilitator for the adults, or by jumping into a Kids Core Class (returning in 2024) and helping us teach the next generation.

What is next after Core Classes?

While challenging, these Core Classes are only scratching the surface of the deep riches that God has revealed in His Word. Both the Core Scripture and Core Doctrine classes are quick overviews of biblical and systematic theology, and we could easily spend well over 11 weeks on any one single topic addressed in those classes.

That said, we’ve launched a one-year program—Academy—that is available to church members who have completed both Core Scripture & Core Doctrine classes. Academy is designed to be a more intensive and rigorous program than our Core Classes. They will be a limited class size, and you will need to apply (vs register) to participate. (The next round of Academy will open in the Fall of 2024)

In the meantime, reference the bonus resources in the appendixes of your Core workbooks for recommended reading on specific subjects to go deeper on your own.
