St. Isidore's parish has been the bishop's home for the past five years.
Nearly 100 young people participated in the Millennial Missionaries 2017 event at the Basilica of the Sacred Hearts of Jesus and Mary.
Cardinal Rosa Chavez said some youths turn to gangs to get the love and affirmation they do not receive at home.
"The measure of our commitment to the Gospel will shine forth in the days and weeks to come."
Bishop Barres offered prayers and warm congratulations to Bishop Naickamparambil.
