Here's some excellent info on the Saints (excerpts):
Thus, when St. Justin looks at the Lives of the Saints, he does so in the light of the God-man. Real and true lifeeternal life in Godbecame possible only with the Incarnation, death and Resurrection of the Saviour, and this life is the Life of the Saints. St. Justin saw the Lives of the Saints as bearing witness to one life: the Life in Christ.
St. Justin wrote: "What are Christians? Christians are Christ-bearers, and, by virtue of this, they are bearers and possessors of eternal life. The Saints are the most perfect Christians, for they have been sanctified to the highest degree with the
podvigs of holy faith in the risen and eternally living Christ, and no death has power over them. Their life is entirely Christ's life; and their thought is entirely Christ's thought; and their perception is Christ's perception. All that they have is first Christ's and then theirs. In them is nothing of themselves but rather wholly and in everything the Lord Christ." [1]
The Saints live in Christ, but Christ also lives in them through His Divine Energies, His Grace. And where Christ is, there is the Father and the Holy Spirit also. Christ says,
Abide in Me, and I in you; and elsewhere He says, If a man love Me, he will keep My words: and My Father will love him, and We will come unto him, and make Our abode with him (John 15:4; 14:23).
This is an amazing thing that St. Justin is saying: when we read the Lives of the Saints, we are reading the Life of our Lord Jesus Christ. This in itself should be enough to convince us of the importance of filling our souls with the Lives of the Saints.
I spoke recently to an Orthodox priest who had converted to Orthodoxy from Protestantism. He told me that, when he was received into the Church, the officiating priest told him: "You will never be truly Orthodox without reading the Lives of the Saints." Later, when he himself became a priest, he found that the most pious people in the churches are those who read the Lives of the Saints, and that those who make the most progress in the spiritual life are those who read the Saints' Lives.
The Orthodox Faith is not, first of all, of the head. First of all, it is of the heart: it is felt
and believed by the heart. Through the Lives of the Saints, we develop an Orthodox heart. Our monastery's co-founder, Fr. Seraphim Rose, emphasized constantly this "Orthodoxy of the heart," especially in his writings and talks at the end of his life; and he frequently referred to Lives of the Saints as a means of developing this.
St. John (Maximovitch) himself wrote beautiful words about the Saints. These words well express what he saw as the essence of sanctity, as well as the blueprint of his own life. "Holiness is not simply righteousness," St. John wrote, "for which the righteous merit the enjoyment of blessedness in the Kingdom of God, but rather it is
such a height of righteousness that men are filled with the Grace of God to the extent that it flows from them upon those who associate with them. Great is their blessedness; it proceeds from personal experience of the Glory of God. Being filled also with love for men, which proceeds from the love of God, they are responsive to men's needs, and upon their supplication they appear also as intercessors and defenders for them before God." [13]
