The reference to the "light winning over darkness" on the Winter Solstice is based on natural ebb and flow of sunlight on this planet. The longest night and shortest day are the day before the Solstice. The beginning of light returning, and lengthening daylight, is the Solstice.
I understand the dilemma you mention. I also think that Joseph rushed in to correct errors and preserve the group too quickly, and with too much centralized control. Had he allowed others to wander away, the restoration may have included fewer people, but they would have had a greater chance of achieving Zion. For Joseph, the mission was global and he wanted to have the entire human family reached by his ministry. It is apparent, now in hindsight, that the world will never qualify to be gathered. Now the focus must be to find only the very few who, by their patience and heed can qualify to be true, faithful, patient, meek, humble and willing to allow the Lord's timing and not their own control the events.
I know of all the things you mention. I am acquainted with the various things underway, and have some understanding of the errors of each of these various groups. I have not, and will not intervene. They must be allowed to take their own course. In the end, there will be only a few gathered. Those who qualify will have proven themselves true and faithful in all things and prepared to converse with the Lord through the veil.

In response to a question about God not presently having a house on earth, it should be clear this is not a reference to men as the temple of God. God does dwell with some now living.
Nor is it a reference to the various synagogues, cathedrals, chapels, temples and religious facilities constructed by all the various religions in which men practice their rites and devotions to God. Some of those are lovely, quiet and filled with reverence and beauty.
It is a reference to a House God will visit and accept as His. He will appear there, send His messengers (angels) to visit and open a fiery corridor between heaven and earth. Or, in other words, a place where a pillar of fire will dwell.
This was not a criticism of places of worship used by men today. It is an observation of present conditions and a description of what will need to be built and accepted prior to the Lord's return. It will need to be constructed strictly, in accordance with the pattern God requires, and not something men presently construct as their places of worship.
Everything from the location to the details of the design must be according to God's instructions. It will be proof on the earth for heaven to behold, showing to the Powers of Heaven that mankind (however few) are listening to Him and are now willing to do what He asks. God will control if and when it will be done, and who will be permitted to construct His House. This will not be a volunteer project. God alone will bring it to pass, using means determined by Him.
There must be a site prepared, and an invitation extended, before the Lord's return. That place must be hallowed. It is a necessary precondition for His return. It is from that site the sanctification of the earth will proceed. Eventually the whole earth will be renewed.
