We don't need to be super heroes because we have The Cross. It is the most powerful weapon that exists in the universe.
Jesus has already won the battle. He has already defeated evil, darkness, every single power, every single principality, and every single force of darkness that exists in this entire universe once and for all on the Cross. That is what we celebrate in the liturgy.
We offer ourselves to God as a sacrifice to God. We offer all of humanity to God. This is how we share in the priesthood.
