There is much that can be taken from Star Wars and applied to the Church, some rightly and some wrongly. But for today, I would like to draw a comparison in faith between two beloved characters: R2D2 and C3PO.
R2D2 is what we want to be: he is brave, he is loyal, he is willing to go right through a raging battle in an effort to help his friends.
C3PO is normally what we are: he is scared, he is loyal to the one in power; he rarely goes into a battle, and can often be found staying home or in the safety of the military base while others go into battle.
To put this in terms of our Christian faith: R2D2 is what we are called to be in our baptisms; he is the saint in us that wants to do what is right. C3PO is our Old Adam; he is the sinner in us that wants to do what best suits us.
And so what we see in the Star Wars movies is that R2D2 must constantly push C3PO to do what is right, to do what must be done in an effort to help the Jedi. In Episode 2, it is R2D2 that forces C3PO to enter the droid factory on Geonosis; and in Episode 6, it is R2D2 who bravely enters the lair of Jobba the Hut, while C3PO is seemingly tricked to go along.
R2D2 is the example of faith that we strive for: we strive to confess our faith with boldness, even in the face of those who would do us harm. We strive to say no to drugs, no to premarital sex, no to sin in the face of temptation.
C3PO is the example of avoiding those situations: yes, you are still alive, but how has the faith benefited by your actions?
It is important to note that just as the Jedi are always there to save R2D2 and C3PO when they get in trouble; our Savior Jesus is always there to save us from the consequences of our sins. In those moments of temptation; in those moments where the devil seems to have us trapped; there is Jesus, on the cross, suffering and dying and rising to save us from sin, death and the devil.
Strive to have the faith of R2D2; repent of your moments as C3PO, and always cling to the cross of Jesus.
