Dear Brothers,
I have 
convoked you to this Consistory, not only for the three canonizations, 
but also to communicate to you a decision of great importance for the 
life of the Church. After having repeatedly examined my conscience 
before God, I have come to the certainty that my strengths, due to an 
advanced age, are no longer suited to an adequate exercise of the 
Petrine ministry. I am well aware that this ministry, due to its 
essential spiritual nature, must be carried out not only with words and 
deeds, but no less with prayer and suffering. However, in today’s world,
 subject to so many rapid changes and shaken by questions of deep 
relevance for the life of faith, in order to govern the bark of Saint 
Peter and proclaim the Gospel, both strength of mind and body are 
necessary, strength which in the last few months, has deteriorated in me
 to the extent that I have had to recognize my incapacity to adequately 
fulfill the ministry entrusted to me. For this reason, and well aware of
 the seriousness of this act, with full freedom I declare that I 
renounce the ministry of Bishop of Rome, Successor of Saint Peter, 
entrusted to me by the Cardinals on 19 April 2005, in such a way, that 
as from 28 February 2013, at 20:00 hours, the See of Rome, the See of 
Saint Peter, will be vacant and a Conclave to elect the new Supreme 
Pontiff will have to be convoked by those whose competence it is.
