The interview treats about the necessity of the spiritual life renewal and about the tentative made by the Church in the favor of this renewal. Pigna underlines the fact that the Church has responded to the problems of man of every century. Through the Perfectae caritatis Decree the Church calls out to a spiritual renewal both the clergy and the believers regarding a unity and harmony based on charity. The Council offers precise indications to be putted into action: the fight against formality, the follow of Christ, the return to Gospel. After the Council, the popes along with the bishops have re-attested this necessity, advising to a life style based on charity activity.
