It's all about us. It's a "testament to a believer's faith."
Communion, or the Lord’s Supper, is an ordinance given to all believers by Jesus Christ to remember his sacrifice for us and to symbolize the new covenant. The elements of bread and wine or juice are symbols of Christ’s broken body and shed blood. Communion is not a means of salvation. Rather, it is a testament of a believer’s faith in the atoning work of the cross.
Saddleback is a baptist church, and baptists don't do sacraments. They basically adhere to the perspectives of Greek philosophy which consider the material realm--the physical and fleshy--to be corrupt and inferior to the "purer and higher" spiritual realm. From an historical Christian perspective, this is the gnostic heresy. It's not for nothing that many baptist churches are built to look like Greek temples.
