Solus Christus or In Christo solo (Latin in + ablative, sōlō Christō, meaning "in Christ alone") is one of the five solae that summarize the Protestant Reformers' basic belief that salvation is by faith in Christ alone.[1]
Through the atoning work of JesusChrist alone, apart from individual works, and that Christ is the only mediator between God and man.[1][2] It holds that salvation cannot be obtained without Christ.[1][3]
As the foundation of the "solus christus" doctrine, various biblical verses can be invoked according to theologians.
John 14:6 – "Jesus replied: I am the way, the truth and the life. No one comes to the Father except through me."
First Epistle to Timothy 2:5 – "Because there is only one God, and only one mediator between God and men, the man Christ Jesus."
Acts 4:10–12 – "May all of you and all the people of Israel know that this happened in the name of Jesus Christ of Nazareth […] And there is no salvation in anyone else; for there is no other name under heaven given among men by which we must be saved"
