I had referred in a previous post in this mini-series that our guardian angels will accompany us both at our particular judgement and the final one. Here is the needed second reference. The previous post is found here.
The text on The Last Four Things, which I have just found this morning, referring to the fact that our guardian angels will be with us, is from Chapter Nine of this book by....
FATHER MARTIN VON COCHEM, O.S.F.C.
The guardian angels will lead those who have been committed to their charge to the judgment-seat of God, and then the just will fall before Him in lowly adoration. The evil enemy will then begin to accuse them, and bring forward everything that he can against them. But the guardian angel will defend his client, he will produce all his good works, his penances, his virtues, and lay them in the scales of divine justice. And if they are not too light, Christ will array him in the new robe, the garment of splendor, and crown him with the diadem of the eternal kingdom. Who can tell what the glory of that moment will be ! How all the just will rejoice that their lot is among the blessed ! How kindly the choir of angels will congratulate them, and exult with them in blissful jubilation. And how all who are yet waiting for their sentence will marvel at the glory that is theirs, and long to share it with them.
Both of these quotations are not part of the infallible doctrines of the Church, but part of saintly meditations.
