What are the essential beliefs of the Christian faith?

The essential beliefs of the Christian faith, often articulated through the lens of the 'common faith,' include several core tenets. These are the belief that Jesus Christ is God, that He is also fully man without sin, and that He is the only mediator between God and humanity. As highlighted in the sermon, believers must acknowledge His lordship and His role in representing humanity before God for salvation. These beliefs are not merely doctrinal points but are critical for genuine faith. The understanding that Christ is sinless ensures the efficacy of His atoning sacrifice, and recognizing Him as Lord affirms His authority over all creation and salvation.
