How to get more than the last element of a list

I have this list of lists and when I used this code I only get the last element of the list

//////////////////////////////////////////////////////////// APEX CODE ////////////////////////////////////////////////////////////////////////////////////   
private List<List<MinistrySharesSummary>> ListCollector (List<MinistrySharesSummary> suggestedAmountsList){
        List<List<MinistrySharesSummary>> classisList = new List<List<MinistrySharesSummary>>();
        List<MinistrySharesSummary> churchList = new List<MinistrySharesSummary>();
        
        String tempParent = suggestedAmountsList.get(0).parent;
        for(MinistrySharesSummary ms : suggestedAmountsList){
            
            if(ms.parent == tempParent ){
                churchList.add(ms);     
            }
            else{
                classisList.add(churchList);
                churchList.clear();
                churchList.add(ms);
                tempParent = ms.parent;
            }
        }
        
        return classisList;
    }

Because the churchlist is passed to the classisList by reference, calling "clear" on the list clears it in the list of lists as well. Instead, declare church list as a new list.

//////////////////////////////////////////////////////////// APEX CODE ////////////////////////////////////////////////////////////////////////////////////   
private List<List<MinistrySharesSummary>> ListCollector (List<MinistrySharesSummary> suggestedAmountsList){
        List<List<MinistrySharesSummary>> classisList = new List<List<MinistrySharesSummary>>();
        List<MinistrySharesSummary> churchList = new List<MinistrySharesSummary>();
        
        String tempParent = suggestedAmountsList.get(0).parent;
        for(MinistrySharesSummary ms : suggestedAmountsList){
            
            if(ms.parent == tempParent ){
                churchList.add(ms);     
            }
            else{
                classisList.add(churchList);
                churchList = new List<MinistrySharesSummary>();
                churchList.add(ms);
                tempParent = ms.parent;
            }
        }
        
        return classisList;
