Yes, the public gets to view the rooms during open house.... however, only mormon's with a temple recommend are allowed to witness the rite's being performed or participate in those rites. Those who do not have a temple recommend are told to wait outside as are non-mormon's. It isn't the viewing of the rooms that is the concern here, but the rites, themselves.
What is said and done in those rituals, certainly raises eyebrows.
Would the service rendered to God in this temple, both day and night---by those who are dressed in white robes--raise your eyebrows?
Revelation 7:13-15---King James Version
13 And one of the elders answered, saying unto me,
What are these which are arrayed in white robes? and whence came they?
14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
15 Therefore are they before the throne of God,
and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them.
And those who are participants and those who perform the rituals, are not supposed to talk about them to others.
How could they--and this be true?
Revelation 2:17---King James Version
17 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written,
which no man knoweth saving he that receiveth it.
New Day--the critics here haven't the first living, mortal apostle nor prophet--not the first heavenly revelation they can show within their denominations, no formal priesthood, no temple--nothing the first century church enjoyed, in that respect--which The Church of Jesus Christ of Latter-day Saints also enjoys.
So--could you explain to us how your approach to those things--is any different than what the traditional Jews were leveling against the living, mortal apostles and prophets of the first century church?
And--it's usually those who do not have those things--which level this very accusation against the very Church which does possess them.
When you can post for us--where your church received these kinds of things--then perhaps you might boast of something:
D&C 110
1 The veil was taken from our minds, and the eyes of our understanding were opened.
2 We saw the Lord standing upon the breastwork of the pulpit, before us; and under his feet was a paved work of pure gold, in color like amber.
3 His eyes were as a flame of fire; the hair of his head was white like the pure snow; his countenance shone above the brightness of the sun; and his voice was as the sound of the rushing of great waters, even the voice of Jehovah, saying:
4 I am the first and the last; I am he who liveth, I am he who was slain; I am your advocate with the Father.
5 Behold, your sins are forgiven you; you are clean before me; therefore, lift up your heads and rejoice.
6 Let the hearts of your brethren rejoice, and let the hearts of all my people rejoice, who have, with their might, built this house to my name.
7 For behold, I have accepted this house, and my name shall be here; and I will manifest myself to my people in mercy in this house.
8 Yea, I will appear unto my servants, and speak unto them with mine own voice, if my people will keep my commandments, and do not pollute this holy house.
9 Yea the hearts of thousands and tens of thousands shall greatly rejoice in consequence of the blessings which shall be poured out, and the endowment with which my servants have been endowed in this house.
10 And the fame of this house shall spread to foreign lands; and this is the beginning of the blessing which shall be poured out upon the heads of my people. Even so. Amen.
11 After this vision closed, the heavens were again opened unto us; and Moses appeared before us, and committed unto us the keys of the gathering of Israel from the four parts of the earth, and the leading of the ten tribes from the land of the north.
12 After this, Elias appeared, and committed the dispensation of the gospel of Abraham, saying that in us and our seed all generations after us should be blessed.
13 After this vision had closed, another great and glorious vision burst upon us; for Elijah the prophet, who was taken to heaven without tasting death, stood before us, and said:
14 Behold, the time has fully come, which was spoken of by the mouth of Malachitestifying that he [Elijah] should be sent, before the great and dreadful day of the Lord come
15 To turn the hearts of the fathers to the children, and the children to the fathers, lest the whole earth be smitten with a curse
16 Therefore, the keys of this dispensation are committed into your hands; and by this ye may know that the great and dreadful day of the Lord is near, even at the doors.
The fact is--your church can't show one iota of those kinds of heavenly interactions--because they don't have them. Think on that--a church which claims to be the church of Jesus Christ--which can't show one heavenly interaction--which is canonized as scripture. The NT church can--and so can The Church of Jesus Christ of Latter-day Saints.
Until then--you are shooting blanks.
