Christ Alone (Solus Christus)
Who is the mediator of God's elect? According to 1 Timothy 2:5, there is only one mediator between God and Man, the man Christ Jesus. Jesus stands in the middle, as the bridge between God and Man. God blesses us in Christ, and we pray to God in Christ's name. Through Christ, God communicates with us, and we with Him.
In ancient times, as like the time of the Ancient Near-East (ANE) and in fact ancient societies in general, mankind had the primeval understanding (the remnant of the revelation to Noah) that not any Tom, Dick or Harry could have access to God or the gods. That is the function of priests, who mediate between the people and the divine. It was because the common people could not have access to the gods that they came to embrace lesser deities as household gods. Still there was a general understanding that not anyone could come before the gods as and when they please. Sacrifices had to made, rituals done, before the worshiper could come before the divine, through the mediation of the priests who did all these on his behalf.
In the first century AD, Christianity came onto the scene with its strict monotheism, proclaiming that the office of priests were obsolete (both Jewish and pagan) since Christ is the only mediator that anyone needs to approach God. Old habits die hard however. After Christianity became the state religion of the Roman Empire, many who had undergone a surface conversion saw God as remote and perceived the emerging cult of saints to be a viable alternative as a way of mediation with Christ who is God. Fast forward to the 16th century AD, and we see Mary and the saints treated as lesser mediators, to mediate between the people and Christ, who in turn is supposed to mediate with God the Father for them. Mary, who is both feminine and the mother of Jesus Christ, was seen as the best mediator due to the association of compassion with femininity and her closeness to Jesus. Now, in the 16th century AD, Mary had not yet been declared to be born sinless (that came at Vatican I), yet her exalted place for devotion was already present.
In light of such a corruption of biblical mediation, the Reformation proclaimed that Christ alone is our mediator. Over and against Mary and the saints, the Reformers insisted with 1 Timothy 2:5 that there is only one mediator, who is Christ. Mary and the saints do not mediate anything for anyone, for they themselves are sinners saved by God's grace, and have no right or merit to usurp Christ's office as priest.
In response, a common argument from Roman Catholics is that Mary and the saints are just intercessors, and asking them to pray for us is no different from a person asking his friend to pray for him. But that is to misunderstand what is actually going on in devotion to Mary and the saints. When someone asks his friend to pray for him, he does not pray to the friend to pray for him! He does not give devotion to that friend either. Thus, the mere fact that devotion is given to Mary and the saints imply that such is no mere asking for prayer, but rather the devotee is treating them as lesser mediators, so that they can mediate between him and Jesus.
The Reformation call of Christ Alone has implications beyond Roman Catholicism. If Christ is the only mediator, then that implies that Christianity is the only way of salvation, through the atoning work of Christ. But there is another implication for us today, an implication which was seen against the Socinians, the radical rationalist wing of Anabaptism.
The Socinians were a group of unitarians and Arians, who deny the Trinity and see only the Father as God. Jesus was just an exalted man in their system. But if an exalted man is the mediator, then that implies that mediation is not really necessary. In fact, their rationalism itself is a denial of mediation, in that Man does not need God to gain knowledge. Instead of having many mediators, and a hierarchy of mediation as in Roman Catholicism, Socinians reject mediation altogether. And if mediation is unnecessary, that means that God is not necessary for living life. God might be present, his law still is useful, but Man can through his own effort work on his own betterment, and attain the good life on his own.
It is here that we see another relevance of the principle of Christ Alone for us today. Today, it is not the Roman Catholic view of mediation that has won. Rather, it is the Socinian view of mediation that rules the world. Even in many Evangelical churches, worshipers think that God must accept them just as they are. There is no sense of a need for mediation, that they can come and worship God only because Jesus mediates between them and God. Especially in the Third Wave Charismatic circles, there is the strange idea that one can "encounter God" just because one is a Christian, presuming upon God's grace and Christ's mediation without the attitude of godly fear that one is coming before a holy God, and that any meeting with God (if any) should not be taken for granted. God is God, not a genie in a bottle for our enjoyment, and it is very sad when professing believers treat God no different from how a genie is to be treated.
As we remember the 500th anniversary of the Reformation, let us hold firm to the principle of Christ Alone, not just for the exclusivity of Christ, but also in recognition that mediation remains necessary. The modern world has lost its concept of mediation and has rejected the notion of priests. Christians do not have priests, but we do have one great high priest in our Lord Jesus Christ. Therefore, let us attend to the things of God reverently, and remember we are still creatures living dependently before Almighty God. Amen.
