A - Thanks for the question. It depends on how we define frustration. If frustration is an emotion which comes from some external opposition, then we could say that Jesus did get frustrated.
One principle that might help is to understand that emotions, in and of themselves, are not either morally good or bad. They are morally neutral. It is our reaction to them that is either good or bad.
The Catechism says:
1768 Strong feelings are not decisive for the morality or the holiness of persons; they are simply the inexhaustible reservoir of images and affections in which the moral life is expressed. Passions are morally good when they contribute to a good action, evil in the opposite case. the upright will orders the movements of the senses it appropriates to the good and to beatitude; an evil will succumbs to disordered passions and exacerbates them. Emotions and feelings can be taken up into the virtues or perverted by the vices.The classic case of seeing Jesus respond to a situation emotionally (yet still morally justified) is in the Temple when He overturns the money changers tables:
I would expect that Jesus was frustrated, angry, and upset by his Father's temple becoming a place of lies, theft, and dishonesty. This is a righteous anger and no sin is committed. In fact, to allow injustice to flourish without fighting against it is the sin here - not the feelings of frustration or anger.
Matt 21: 12-13
Sometimes we have an understanding of Jesus as too sugary-sweet. As if He skips around with flowers, singing that he would like to buy the world a Coke and world peace. This isn't the case. Christ fought for His justice not just for mercy.
Was Jesus kind? Absolutely. Was Jesus nice? Not all the time - because "nice people" don't get crucified.
"Be angry, and sin not." -Eph 4:26I hope this helps.
