text: ...."The laity cannot consecrate and can only administrate"...
  
  The people appointed by the 12 Apostles and Paul to lead the early Church communities were all 'laity'. 'Clerics' had not been invented as yet.
  
  According to Vatican 2 the Bishop is the 'THE Priest' of the Diocese.
   
  The Bishop then delegates his powers of teaching and administration and administering sacraments to others - as determined by the customs developed over centuries and encoded in 'Canon Law'.
  
  Custom, as enshrined in Canon Law, has set up a 'clerical' system for those parts of his powers that a Bishop delegates to a 'priest' or 'deacon'. 
  
  But customs can and have changed. Many of a Bishop's Administrative functions are now  delegated to non-cleric 'laity'. Qualified Laity 'teach',  in Schools and Universities, and in the parish. Laity give marriage prep. They lead RCIA classes They are Communion Ministers.
  
  In short, 'laity' do whatever a Bishop delegates them to do. He CAN choose to 'ordain' non-cleric laity.
