81 Priests should reflect on the advice of the Council, (134) which reminds them of their common sharing in the priesthood so that they may feel a lively responsibility for fellow priests troubled by difficulties which gravely endanger the divine gift they have. They should have a burning charity for those who have greater need of love, understanding and prayer, who have need of prudent but effective help, and who have a claim on their unbounded charity as those who are, and should be, their truest friends.
