Scottish Football Association chief executive Stewart Regan wants an end to the backbiting that has dogged the game this year and for focus to return to reconstruction.
Rangers' demise and the subsequent placing of Charles Green's newco into the Irn-Bru Third Division this summer provoked unprecedented animosity and acrimony.
Regan found himself at the centre of much criticism, with Rangers boss Ally McCoist saying last week, after the relaunched Govan club had been granted conditional SFA membership: "In recent days, I have been in a number of meetings with Stewart Regan, Rod Petrie and other senior SFA figures - and despair at the lack of leadership shown."
Green did little to ease the ill-feeling swirling around the game when, before Sunday's Ramsdens Cup extra-time win over Brechin at Glebe Park, the Rangers chief executive suggested that the reason the Ibrox club were denied entry into the Scottish Premier League was due to bigotry and jealousy.
The SFA's compliance officer, Vincent Lunny, has written to Green asking him to explain his comments.
In a statement released to Press Association Sport, Regan, who was handed a vote of confidence by the SFA board, said: "Comments in recent weeks have been undignified and irresponsible but it is important we now look ahead and focus our attention on football. It has been a challenging summer and one that we all have learned from.
"But we are where we are and the Scottish FA as a governing body now has the responsibility to unite everyone in Scottish football - league bodies, clubs, supporters - and help take the game forward.
"We need to restore faith and trust among the three bodies and we are committed to reconstruction and a solution in the best interests of all 42 senior clubs and those who are inspired to join senior football.
"Of course it has been challenging for the Scottish FA and myself but it is important to emphasise the facts behind the popular misconception. The Five-way agreement was exactly that. The Scottish FA played the role of peacekeeper between the SPL and the SFL along with Rangers oldco and Rangers newco.
"Those discussions culminated in a presentation to all member clubs and the outcome was Rangers being accommodated in Division Three. Throughout the process the Scottish FA's only priority was to look after the best interests of the whole of the game and to ensure 42 clubs did not suffer in the circumstances that affected one club."
