In relation to sacraments, how should Christians express their faith?

The correct choice emphasizes that Christians should express their faith in relation to sacraments through faith while observing them as directed in Scripture. This reflects the core understanding of sacraments in many Christian traditions, particularly in Reformed theology, which strongly aligns with the principles outlined in the Westminster Shorter Catechism.

Sacraments, such as baptism and the Lord's Supper, are outward signs instituted by Christ to convey inward grace. The emphasis on observing them "as directed in Scripture" highlights the importance of adhering to biblical instructions and understanding the theological significance behind each sacrament. This perspective underscores that faith is not just a personal experience but is also communal, as it engages the believer in both personal conviction and the larger body of the Church.

The other options introduce elements that do not fully align with this understanding. Focusing solely on communal gatherings limits the personal aspect of faith, while emphasizing individual reflection without any practice overlooks the communal and outward expressions of faith that sacraments represent. Similarly, relying solely on church traditions without basing practices in Scripture can lead to a disconnect from the foundational truths that sacraments are meant to convey.
