Sometimes we make things into victories and completely miss the true victory. Kateri was a Native American who became Catholic, nothing more, nothing less. It is not proof of the power of missionaries, nor the power of one faith or denomination over another, nor the power of Western culture over Native culture, nor any other number of things.
It is, however, a victory for God and God's love.
I am not my own; I have given myself to Jesus. He must be my only love. The state of helpless poverty that may befall me if I do not marry does not frighten me. All I need is a little food and a few pieces of clothing. With the work of my hands I shall always earn what is necessary and what is left over I'll give to my relatives and to the poor. If I should become sick and unable to work, then I shall be like the Lord on the cross. He will have mercy on me and help me, I am sure.
