If you want to avoid Jansenism develop a devotion to St Philip.
He is known as the second Apostle of Rome, contributing to that extraordinary movement of the city from scandalous corruption to a city of devotion and sanctity. He is the only saint to have written a joke book, he made religion fun. He gathered about him proud aristocratic Roman youths and taught them to laugh at themselves. Even saints like Ignatius of Loyola, he taught to smile at themselves.
There is something incredibly human about him, he could convert sinners just by holding them to his breast listening to his heartbeat.
