From the Round Dance of the Cross:

Jesus told us to form a circle and hold each other's hands, and he himself stood in the middle and said:

....
"I will be wounded and I will wound"
"Amen"
"I will eat and I will be eaten"
Amen

These two sayings are interesting because I see them as both having a double meaning, one for the less spiritually advanced, for those still struggling with ignorance, and another for those as they rise above their struggles.

The acknowledgement that "I will wound and be wounded" is perhaps saying that we will continue to sin and separate ourselves from others and from God. It is a confession of our faults and imperfection. Accepting the message of Christ does not lead to an automatic cessation of our sin-desires nor does it defeat them. Yet, it is perhaps additionally alluding to the wounds of Christ himself and imlpying that not only will we be crucified with his wounds but that we ourselves will be the one's driving in those nails, so to speak and indeed, that we will be helping to crucify or "wound" others.

"I will eat and I will be eaten" recalls the saying from the Gospel of Thomas that "blessed is the lion if a human eats its". It could be an acknowledgement of the struggle against our bestial nature, that we encounter both moments of defeat and are "eaten by it" as well as victory. Again, this could be read as acknowledgement of the human condition as it stands in the more uncertain and immature stages of the spiritual journey when one has not mastered their self despite their committment to Christ.
