I am willing to accept the testimony of the Fathers of the Church as to the dogma of the Trinity, Christology, Mary as Theotokos (not Christokos), as well as the final canon of the New Testament Scriptures. So I am also able to accept their testimony concerning the intercession and invocation of the saints. I believe DHK has expressed concern regarding relying on the ECF's for anything. Some of them did indeed hold to some heretical views, but those views were debated and brought to the light. Nobody ever debated the validity of the invocation of the saints.
So at what point do these fallen men cease being quotable and citable and become unreliable and heretical? Throw the baby out with the bathwater? I certainly think that is what happened at the Reformation.
I found in my studies that asking saints to pray for us is supported by writings of the same men who were the defenders and promoters of the Nicene Creed. The Fathers that had suffered, struggled, and even died for the doctrine of the Trinity, and the full divinity of Jesus and the Holy Spirit, those who described this relationship in language too rarified for me to fully comprehend to this day. And in the face of all else we disagree upon, most here would agree on the these dogmas (Trinity, Christology) as pounded out by these men.
The Patristic and Scriptural Testimony:
Book of Tobit (~ 200 – 100 BC)
When thou didst pray with tears… I [Archangel Raphael] offered thy prayer to the Lord.[12]
St. John the Evangelist (+101)
And another angel came, and stood before the altar, having a golden censer; and there was given to him much incense, that he should offer of the prayers of all saints upon the golden altar, which is before the throne of God. And the smoke of the incense of the prayers of the saints ascended up before God from the hand of the angel.[13]
Eygptian Liturgy for the Nativity of Christ (200 AD)
Beneath thy tenderness of heart
we take refuge, O Theotokos,
disdain not our supplications in our necessity,
but deliver us from perils,
O only pure and blessed one.
St. Ephraim the Syrian (+373)
Remember me, ye heirs of God, ye brethren of Christ, supplicate the Saviour earnestly for me, that I may be freed though Christ from him that fights against me day by day.[14]
Ye victorious martyrs who endured torments gladly for the sake of the God and Saviour; ye who have boldness of speech towards the Lord Himself; ye saints, intercede for us who are timid and sinful men, full of sloth, that the grace of Christ may come upon us, and enlighten the hearts of all of us that so we may love him.[15]
St. Cyril of Jerusalem (+386)
We then commemorate also those who have fallen asleep before us, first, patriarchs, prophets, apostles, martyrs, that God, by their prayers and intercessions, may receive our petitions.[16]
George Bebis on the Cappadocian Fathers
“In one of his letters, St. Basil (+379) explicitly writes that he accepts the intercession of the apostles, prophets and martyrs, and he seeks their prayers to God. (Letter 360) Then, speaking about the Forty Martyrs, who suffered martyrdom for Christ, he emphasizes that they are common friends of the human race, strong ambassadors and collaborators in fervent prayers. (Chapter 8)
“St. Gregory of Nyssa (+395-400) asks St. Theodore the Martyr …to fervently pray to our Common King, our God, for the country and the people (Encomium to Martyr Theodore).
“The same language is used by St. Gregory the Theologian (+390) in his encomium to St. Cyprian. (Gen. 44: 2 and Encomium to Julian, Iuventinus and Maximinus, 3).”[17]
St. Basil the Great, of Caesarea in Asia Minor (+379)
According to the blameless faith of the Christians which we have obtained from God, I confess and agree that I believe in one God the Father Almighty; God the Father, God the Son, God the Holy Ghost; I adore and worship one God, the Three. I confess to the oeconomy of the Son in the flesh, and that the holy Mary, who gave birth to Him according to the flesh, was Mother of God. I acknowledge also the holy apostles, prophets, and martyrs; and I invoke them to supplication to God, that through them, that is, through their mediation, the merciful God may be propitious to me, and that a ransom may be made and given me for my sins. Wherefore also I honour and kiss the features of their images, inasmuch as they have been handed down from the holy apostles, and are not forbidden, but are in all our churches.[18]
We beseech you, O most holy martyrs, who cheerfully suffered torments and death for his love, and are now more familiarly united to him, that you intercede with God for us slothful and wretched sinners, that he bestow on us the grace of Christ, by which we may be enlightened and enabled to love him.[19]
O holy choir! O sacred band! O unbroken host of warriors! O common guardians of the human race! Ye gracious sharers of our cares! Ye co-operators in our prayer! Most powerful intercessors![20]
St. Gregory the Theologian, Patriarch of Constantinople; of Nazianzus in Asia Minor (+389-390)
Mayest thou [Cyprian] look down from above propitiously upon us, and guide our word and life; and shepherd [or shepherd with me] this sacred flock . . . gladdening us with a more perfect and clear illumination of the Holy Trinity, before Which thou standest.[21] [“In like manner does Gregory pray to St. Athanasius (Orat. xxi, "In laud. S. Athan.", P.G., XXXV, 1128).][22]
“...we should here bear in mind Bellarmine's remarks: "When we say that nothing should be asked of the saints but their prayer for us, the question is not about the words, but the sense of the words. For as far as the words go, it is lawful to say: 'St. Peter, pity me, save me, open for me the gate of heaven'; also, 'Give me health of body, patience, fortitude', etc., provided that we mean 'save and pity me by praying for me'; 'grant me this or that by thy prayers and merits.' For so speaks Gregory of Nazianzus (Orat. xviii — according to others, xxiv — "De S. Cypriano" in P. G., XXXV, 1193; "Orat. de S. Athan.: In Laud. S. Athanas.", Orat. xxi, in P. G., XXXV, 1128); in "De Sanct. Beatif.", I, 17. … In like manner does Gregory pray to St. Athanasius (Orat. xxi, "In laud. S. Athan.", P. G., XXXV, 1128).”[23]
St. Gregory of Nyssa in Lower Armenia (+395-400)
...I wish to commemorate one person who spoke of their noble testimony because I am close to Ibora, the village and resting place of these forty martyrs' remains. Here the Romans keep a register of soldiers, one of whom was a guard ordered by his commander to protect against invasions, a practice common to soldiers in such remote areas. This man suffered from an injured foot which was later amputated. Being in the martyrs' resting place, he earnestly beseeched God and the intercession of the saints. One night there appeared a man of venerable appearance in the company of others who said, "Oh soldier, do you want to be healed [J.167] of your infirmity? Give me your foot that I may touch it." When he awoke from the dream, his foot was completely healed. Once he awoke from this vision, his foot was restored to health. He roused the other sleeping men because he was immediately cured and made whole. This men then began to proclaim the miracle performed by the martyrs and acknowledged the kindness bestowed by these fellow soldiers…. We who freely and boldly enter paradise are strengthened by the [martyrs'] intercession through a noble confession in our Lord Jesus Christ, to whom be glory forever and ever. Amen.[24]
Do thou, [St. Ephraim the Syrian] that art standing at the Divine altar, and art ministering with angels to the life-giving and most Holy Trinity, bear us all in remembrance, petitioning for us the remission of sins, and the fruition of an everlasting kingdom.[25]
St. Ambrose of Milan (+397)
May Peter, who wept so efficaciously for himself, weep for us and turn towards us Christ's benignant countenance.[26]
St. John Chrysostom, Patriarch of Constantinople; b. Antioch, Syria (+407)
When thou perceivest that God is chastening thee, fly not to His enemies . . . but to His friends, the martyrs, the saints, and those who were pleasing to Him, and who have great power [parresian, "boldness of speech"].[27]
He that wears the purple, laying aside his pomp, stands begging of the saints to be his patrons with God; and he that wears the diadem begs the Tent-maker and the Fisherman as patrons, even though they be dead.[28]
“[St. John] says that we should seek the intercession and the fervent prayers of the saints, because they have special "boldness" (parresia), before God. (Gen. 44: 2 and Encomium to Julian, Iuventinus and Maximinus, 3).”[29]
St. Jerome (+419)
If the Apostles and Martyrs, while still in the body, can pray for others, at a time when they must still be anxious for themselves, how much more after their crowns, victories, and triumphs are won! One man, Moses, obtains from God pardon for six hundred thousand men in arms; and Stephen, the imitator of the Lord, and the first martyr in Christ, begs forgiveness for his persecutors; and shall their power be less after having begun to be with Christ? The Apostle Paul declares that two hundred three score and sixteen souls, sailing with him, were freely given him; and, after he is dissolved and has begun to be with Christ, shall he close his lips, and not be able to utter a word in behalf of those who throughout the whole world believed at his preaching of the Gospel? And shall the living dog Vigilantius be better than that dead lion?[30]
The testimony is indeed overwhelming and the FACT that requesting the prayers of the saints was NEVER debated by the Church from the time of it's founding and the biblical support leads me to believe that I'm not standing on shaky ground at all
