Cardinal Soane Patita Paini Mafi of Tonga called on the men - from Fiji, the Solomon Islands, Vanuatu, Kiribati, Tonga and Samoa to remember their roles as servants.
"Our Pacific people treat us (priests) as chiefs, matai or nopele and we are thankful to them for that honour," Cardinal Mafi said.
"But never forget that walking in the footsteps of Jesus we must first be servants - servants of the people and servants of God."
Islands Business reports relatives of the men travelled from across the Pacific to attend the ordination.
