He addresses some the issues we’ve been haggling about here, in a way:
In the Incarnation of the Son of God, in fact, we recognize the origins of the Church. Everything began from there. Every historical realization of the Church and every one of her institutions must be shaped by that primordial wellspring. They must be shaped by Christ, the incarnate Word of God. It is he that we are constantly celebrating: Emmanuel, God-with-us, through whom the saving will of God the Father has been accomplished.
And the symbols:
The theme of the relationship between the Petrine principle and the Marian principle is also found in the symbol of the ring which I am about to consign to you. The ring is always a nuptial sign. Almost all of you have already received one, on the day of your episcopal ordination, as an expression of your fidelity and your commitment to watch over the holy Church, the bride of Christ (cf. Rite of Ordination of Bishops). The ring which I confer upon you today, proper to the cardinalatial dignity, is intended to confirm and strengthen that commitment, arising once more from a nuptial gift, a reminder to you that first and foremost you are intimately united with Christ so as to accomplish your mission as bridegrooms of the Church. May your acceptance of the ring be for you a renewal of your "yes", your "here I am", addressed both to the Lord Jesus who chose you and constituted you, and to his holy Church, which you are called to serve with the love of a spouse. So the two dimensions of the Church, Marian and Petrine, come together in the supreme value of charity, which constitutes the fulfilment of each. As Saint Paul says, charity is the "greatest" charism, the "most excellent way" (1 Cor 12:31; 13:13).
And the final reminder, to the cardinals, and to us all:
Everything in this world will pass away. In eternity only Love will remain. For this reason, my Brothers, taking the opportunity offered by this favourable time of Lent, let us commit ourselves to ensure that everything in our personal lives, and in the ecclesial activity in which we are engaged, is inspired by charity and leads to charity. In this respect too, we are enlightened by the mystery that we are celebrating today. Indeed, the first thing that Mary did after receiving the Angel’s message was to go "in haste" to the house of her cousin Elizabeth in order to be of service to her (cf. Lk 1:39). The Virgin’s initiative was one of genuine charity, it was humble and courageous, motivated by faith in God’s word and the inner promptings of the Holy Spirit. Those who love forget about themselves and place themselves at the service of their neighbour. Here we have the image and model of the Church! Every ecclesial community, like the Mother of Christ, is called to accept with total generosity the mystery of God who comes to dwell within her and guides her steps in the ways of love.
