WJoshua 5:10-11 gives absolutely no evidence of any wavesheaf ceremony. According to God's instructions on the matter, the Israelites had nothing acceptable to offer to Him. Any wavesheaf lifted before Him from Gentile-grown grain would have been an abomination!
Deuteronomy 12 absolutely forbids the erection of an altar for the normal ceremonial worship of God until the land had been conquered, Israel had peace, the location of the central sanctuary (the Tabernacle with all its furniture and priests standing to serve) had been determined, and the Tabernacle set up.
Due to the facts that no wavesheaf ceremony was possible, no accompanying sacrifices were permitted, and the Israelites' preparation for the holy-day Sabbath was finished in time, one cannot extrapolate with absolute certainty that that particular Passover occurred on a weekly Sabbath immediately prior to the Feast of Unleavened Bread. Further, one certainly cannot use such an assumption as permission to begin the count to Pentecost from a holy-day Sabbath, which can never be a common workday.
Leviticus 23 specifically states that the wavesheaf must be made on the day after a Sabbath, not on a Sabbath. The present practice of most of the churches of God is so unusual that no one else in the world of Christianity or Judaism may have ever done such a thing.
Basing an important doctrine on symbolism is a shaky proposition in the first place, especially when its application is tied to a lunar calendar with its annual shifting of days and dates. Should we build major doctrines on symbolism or the solidity of a direct statement or example?
Joshua 5:10-11 cannot be used as the basis to change God's firmly set rule established in Leviticus 23:15-16, which says to begin the count to Pentecost with the day following the weekly Sabbath that falls within the Feast of Unleavened Bread. When building on sandy assumptions, the foundation is inherently weak, and the conclusion will crumble when put to the test.
