Today's gospel is about the calling and responding. Certainly, we hear about calling, that is, the vocation in our hearts. Vocation is from latin vocare, which means to call, hence calling. A call, requires a response, but it is a voluntary response. It cannot be imposed as it no longer would be valid, it would lose genuinity. Nonetheless, Andrew meets Jesus, goes for Peter, his brother, and without hesitation; the both of them respond assenting to follow Him. They abandoned absolutely everything to become fishers of men, Jesus—is the calling—and they were the response. How are we going to response to that particular calling? Can we make the ultimate sacrifice to become fishers of men?
