When an ambassador comes to a new country to represent his Head of State, he presents his “credentials” to the president or monarch of the new country where he is. For Eugene the Cross is the “credential” that shows that it is God who is sending the Missionary to be the co-operator of the Savior among the people to whom he is missioning.
This crucifix will serve as the credentials of their ambassadorship to be carried out by them among different peoples to whom they will be sent.
The “credential” is a sign to others, and a reminder to the Missionary himself of his status of being constantly sent by the Savior:
It will not only inspire with respect the people whom they have to evangelize, but it will also be a perpetual reminder to the missionaries themselves of the humility, patience, charity, and all the other virtues which they are called upon to practice in the exercise of their most holy and inspiring ministry.
1818 Rule, Part Two, Chapter One. Regarding other principal observances
Today, after a period of intense formation, the new Oblate receives his “credentials” to share in the Cross of Jesus, whose promises are his hope:
Novitiate formation ends with a free and faith-filled commitment in the Oblate Congregation. The novice, having experienced the Father’s love in Jesus, dedicates his life to making that love visible. He entrusts his fidelity to the one whose cross he shares, whose promises are his hope.

“A witness, in the sense that I am using the word, is a man whose life and faith are so completely one that when the challenge comes to step out and testify for his faith, he does so, disregarding all risks, accepting all consequences.” Whittaker Chambers
