The Feast of the Transfiguration of the Lord...
is today. There is information on it here.

It is a battle which goes on between good and evil, and though by God's grace we do something, we cannot do more. There is confusion of nations and perplexity. It is God's will that so it should be, to show His power. He alone can heal the soul, He alone can expel the devil. And therefore we must wait for a great deal, till He comes down, till He comes down from His seat on high, His seat in glory, to aid us and deliver us.

In that day we shall enter, if we be worthy, the fulness of that glory, of which the three Apostles had the foretaste in the moment of Transfiguration. All is darkness here, all is bright in heaven. All is disorder here, all is order there. All is noise here, and there there is stillness, or if sounds are heard, they are the sweet sounds of the eternal harps on which the praises of God are sung. Here we are in a state of uncertainty: we do not know what is to happen. The Church suffers; her goodly portion, and her choice inheritance suffer; the vineyard is laid waste; there is persecution and war; and Satan rages and afflicts when he cannot destroy. But all this will be set right in the world to come, and if St. Peter could say at the Transfiguration "It is good to be here," much more shall we have cause to say so when we see the face of God. For then we shall be like our Lord Himself, we shall have glorified bodies, as He had then, and has now. We shall have put off flesh and blood, and receive our bodies at the last day, the same indeed, but incorruptible, spiritual bodies, which will be able to see and enjoy the presence of God in a way which was beyond the three Apostles in the days of their mortality. Then the envious malignant spirit will be cast out, and we shall have nothing to fear, nothing to be perplexed at, for the Lord God shall lighten us, and encompass us, and we shall be in perfect security and peace. Then we shall look back upon this world, and the trials, and temptations which are past, and what thankfulness, what joy will not rise within us—and we shall look forward; and this one thought will be upon us that this blessedness is to last for ever. Our security has no limit. It is not that we shall be promised a hundred years of peace, or a thousand, but for ever and ever shall we be as we are, for our happiness and our peace will be founded in the infinite blessedness and peace of God, and as He is eternal and happy, so shall we be.
