The first of these is easy to account for. All Saints Day has had proper texts in the Prayer Book from the beginning in 1549 so, obviously, the Reformers had no objections to it. Secondly, there are countless numbers who have lived especially holy lives - so many that there isn’t room on the Church calendar to accommodate them all in any practical way. Besides, who knows how many saints there are whose virtue has escaped the public notice of the Church? So we have a day to collectively celebrate them all and to thank God for the action of His grace in our lives.
But, it is not simply "their" day. It is ours too. For we are numbered among the saints and, yes, I purposely use the present tense 'are numbered' with good reason, it is Biblical and factual. Romans 1:7 says, "To all that be in Rome, beloved of God, called to be saints: Grace to you and peace from God our Father, and the Lord Jesus Christ." In Colossians 1:1-2 it is written: "Paul, an apostle of Jesus Christ by the will of God, and Timotheus our brother, To the saints and faithful brethren in Christ which are at Colosse: Grace be unto you, and peace, from God our Father and the Lord Jesus Christ."
Rather than just being limited to a list of those formally enrolled (or "canonised") by the Church, all faithful Christian believers everywhere are, and are called to be, saints. To this great dignity, we can only respond with the Apostle John: "See what love the Father has given us, that we should be called children of God; and so we are." (1 John 3:1a)
Yet I know that sounds like a tall, nigh on insurmountable task. And it is, were we simply left to scratch around in the dust of our own devices. But...the God of all grace has and continues to supply the will to "all that believe in Him" to live into the saving faith He has given us and to show it forth in increasing knowledge and good works. Think of it this way, as it is directly akin to that other seemingly impossible directive in Matt. 5:48, "Be ye therefore perfect, even as your Father which is in heaven is perfect." The Rev. William Barclay, in his 'Daily Study Bible', gives us some helpful advice for interpreting and receiving this piece of the Good News. "On the face of it that sounds like a commandment which cannot possibly have anything to do with us. There is none of us who would even faintly connect ourselves with perfection....This word [perfect] is often used in Greek in a very special way. It has nothing to do with what we might call abstract, philosophical, metaphysical perfection....A man who has reached his full-grown stature is [perfect] in contradistinction to a half-grown lad. A student who has reached a mature knowledge of his subject is [perfect] as opposed to a learner who is just beginning, and who as yet has no grasp of things....It is the whole teaching of the Bible that we realise our manhood only by becoming godlike. The one thing which makes us like God is the love which never ceases to care for men, no matter what men do to it. We realise our manhood, we enter upon Christian perfection, when we learn to forgive as God forgives, and to love as God loves." (The Gospel of Matthew vol. 1, 177-178) That too, then, is how we live into our call to sainthood.
Here's where things start getting a little more interesting. The keeping of All Souls Day and some of the attendant customs, ceremonies, and theology surrounding it have been (and continue to be) subject to no little amount of controversy. At its heart, I believe the disputation rests on the question of the purpose of prayer and supplication for those already deceased. As a further subset to that, it seems to me that there is a generic misunderstanding of the nature of what prayer itself actually is. Let me boil this down as simply as I can. Whether you come from a traditional. liturgical church like our own, an Evangelical mega church, an underground fellowship officially persecuted by the local government in some foreign land, or what have you, we all pray. If someone is sick, we pray for them. When we are inspired by the grace of God, we thank Him in prayer. There is a cause and effect relationality to all of our thanks and praise. Need something next week? Ask for it today. Thankful for blessings received yesterday? Be sure to thank the One Who gave them tomorrow. Thus, our prayers are bound up with our existence in time. As this is the only mode of existence we have experienced, it works for us. But what about God’s perspective? In heaven there is no time. God is always present. He wasn’t kidding when He revealed His name to Moses as “I AM” (as opposed to “I WAS” or “I WILL BE”). That means that our next week is present in the mind of God right now and always will be. He sees the future because there is no future for Him. So when we petition Him, we are not seeking to change His mind or alter foreseen events because that is impossible. The gift of prayer, then, is for our benefit. It is ultimately an act expressive of faith, hope and charity. To keep on with the example of prayers of petition, when we ask for needs, we are proclaiming our belief in God. We are living out our grace-infused hope that what He has proposed for our faith is true. We are doing a work of charity by recognizing and responding to the needs of others. In short, we are keeping in communion with them. When we pray, we are acknowledging the Divine ordering of the universe [- no more, and yet no less than that].
Keeping all that in mind, consider this, from 2 Maccabees 12: "[The] noble Judas exhorted the people to keep themselves from sin, forsomuch as they saw before their eyes the things that came to pass for the sins of those that were slain. And when he had made a gathering throughout the company to the sum of two thousand drachms of silver, he sent it to Jerusalem to offer a sin offering, doing therein very well and honestly, in that he was mindful of the resurrection: For if he had not hoped that they that were slain should have risen again, it had been superfluous and vain to pray for the dead." (vs. 42b-44) The context here is that Judas Maccabeus and his men went to engage the governor of Idumea in battle and some of the Jews of Jerusalem were killed and later discovered to have things consecrated to the gods of the Jamnites on their persons. Verse 40 attributes this as the cause of their deaths. Much more significantly, Judas finances a sin offering for these dead, demonstrating his belief in the future bodily resurrection of the dead as well as the charity of praying for their repose. This is a not insignificant instance in the Scriptures and though it is from the Apocrypha - and thus out of bounds for establishing doctrine, per the 6th of the Articles of Religion - it provides a precedent for our very human instinct to remember the dead. Again, as the Articles put it, we can read it for “example of life and instruction of manners”. And thus it leads naturally and directly into our discussion of All Souls Day
Consider what St. Augustine has to say in his work "On the Care of the Dead" wherein he has been discussing what the deceased may or may not continue to be aware of that happens on earth: "Let us not think that anything reaches those deceased for whom we care except what we solemnly pray with our sacrifices – either at the altar, or by our prayers, or by our alms. Yet this does not benefit all for whom such things are done, but only those who prepared for such benefit while they were yet alive. But since we cannot determine who these people are, we ought to do them for all those who have been reborn, so that we do not overlook anyone whom these benefits can and should reach. For it is better to do these things uselessly for people whom they will neither help nor hinder, than to not do them for someone whom they could help." (www.fourthcentury.com/on-the-care-of-the-dead) So, employing here the logic of Pascal's Wager, St. Augustine says it is better to do something potentially superfluous than to neglect something beneficial. Praying for the dead, then, places us in good company with our forebears in faith.
In conclusion, whether we are considering the saints here on earth gathered in the visible body of the Church, those who died and await the fulfilment of their hope in Christ, or those who have come to their reward in heaven, all have in common the possession of the wedding-garment in today's [Trinity XX] Gospel. What that garment might be is described by the Rev. John Boys, sometime Dean of Canterbury during the reign of James I & VI: "The wedding garment, as Origin thinks, is Christ: or as Eusebius, the new man: or as Jerome, observing of the commandments of Christ: or as a pure conversation: or as others, an upright heart, coming to the marriage rather out of duty, than for a dinner: or as others, charity: or as Gregory, grace: or as others, faith: or as others, regeneration: consist in faith and repentance All which upon the point are the very same: so that (as our divines observe) the question is idle whether faith or godly life be this garment, because good works always proceed from faith, and faith always showeth itself by good works." (The Works of John Boys, 758)
And that is the hallmark of which we are reminded by these past liturgical days and by which we are called to order our lives aright: in good works proceeding from faith and that faith showing itself in our God-enabled works.
