Today is the feast of St Cajetan, 1480-1547, the founder of the Theatine Order - one of whose founding members went on to become Pope Paul IV. There is an account of St Cajetan's life here and there is another account from Zenit at Saint Cajetan of Thiene.
He appears to have been like St Philip Neri and other Italian saints and founders of the era in his concern to establish communities to revivify the life of the clergy and the Church and in his practical concern for those around him.
He wrote in a letter to Elisabeth Porto: “Do not receive Christ in the Blessed Sacrament so that you may use him as you judge best, but give yourself to him and let him receive you in this Sacrament, so that he himself, God your saviour, may do to you and through you whatever he wills.”
