Today, January 19 in the Sulpician Liturgical Calendar, is the Memorial of the Interior Life of Jesus. The celebration reflects the desire of the Sulpician founder Jean-Jacques Olier to be more closely united with Jesus Christ, and to adopt his sentiments, attitudes, and interior disposition. Olier’s desire, in fact, reflects a biblical conception rooted in the vision of Saint Paul, who says in his Letter to the Philippians:

If then there is any encouragement in Christ, any consolation from love, any sharing in the Spirit, any compassion and sympathy, make my joy complete: be of the same mind, having the same love, being in full accord and of one mind. Do nothing from selfish ambition or conceit, but in humility regard others as better than yourselves. Let each of you look not to your own interests, but to the interests of others. Let the same mind be in you that was in Christ Jesus…. (Phil 2:1-5 NRSV)
