Cosmas is originally from the diocese of Bunda, a region very close to Lake Victoria in Tanzania.
There he found his vocation to the priesthood and a deep desire to encounter God's grace.
Divine providence brought him to Pamplona to receive a solid and complete priestly formation, something that would have been impossible in Tanzania.
""Here I have received and continue to receive great gifts from God that have changed my life and that I am sure will help me in my future ministry. It has been wonderful to feel how in this time that I have been in Pamplona, my personality has changed, I have made great academic, spiritual and pastoral advances. I am convinced that all of them will lead me to be a good and holy priest to serve God".".
