Because of our commitment to the authority and supremacy of Scripture, our doctrinal commitments and distinctives are summed up in the ecumenical creeds (Apostles’ and Nicene Creeds), the Westminster Standards and the Five Solas of the Reformation.

New Life is led by a plurality of Elders. Whereas Teaching Elders are ministers or pastors called to teach, preach, and administer the sacraments. Ruling Elders are undershepherds called to administer the government of the church and meet the spiritual needs of members of the congregation.


The New Life La Mesa Diaconal board is here to serve the congregation, to provide assistance to those experiencing difficulties and challenges. If you or someone you know is in need of assistance and would like to be contacted by the deacons, please click the button below and fill out the contact form. All requests will be handled discreetly.

Deacons are called ultimately with the purpose of building up and strengthening the Lord’s kingdom. It is our collective desire to be used by God here, today.
