82. It is understandable how the seriousness of the commitment to ecumenism presents a deep challenge to the Catholic faithful. The Spirit calls them to make a serious examination of conscience. The Catholic Church must enter into what might be called a "dialogue of conversion", which constitutes the spiritual foundation of ecumenical dialogue. In this dialogue, which takes place before God, each individual must recognize his own faults, confess his sins and place himself in the hands of the One who is our Intercessor before the Father, Jesus Christ.

Only the act of placing ourselves before God can offer a solid basis for that conversion of individual Christians and for that constant reform of the Church, insofar as she is also a human and earthly institution,136 which represent the preconditions for all ecumenical commitment. One of the first steps in ecumenical dialogue is the effort to draw the Christian Communities into this completely interior spiritual space in which Christ, by the power of the Spirit, leads them all, without exception, to examine themselves before the Father and to ask themselves whether they have been faithful to his plan for the Church.

83. I have mentioned the will of the Father and the spiritual space in which each community hears the call to overcome the obstacles to unity. All Christian Communities know that, thanks to the power given by the Spirit, obeying that will and overcoming those obstacles are not beyond their reach. All of them in fact have martyrs for the Christian faith.137 Despite the tragedy of our divisions, these brothers and sisters have preserved an attachment to Christ and to the Father so radical and absolute as to lead even to the shedding of blood. But is not this same attachment at the heart of what I have called a "dialogue of conversion"? Is it not precisely this dialogue which clearly shows the need for an ever more profound experience of the truth if full communion is to be attained?

84. In a theocentric vision, we Christians already have a common Martyrology. This also includes the martyrs of our own century, more numerous than one might think, and it shows how, at a profound level, God preserves communion among the baptized in the supreme demand of faith, manifested in the sacrifice of life itself.138 The fact that one can die for the faith shows that other demands of the faith can also be met. I have already remarked, and with deep joy, how an imperfect but real communion is preserved and is growing at many levels of ecclesial life. I now add that this communion is already perfect in what we all consider the highest point of the life of grace, martyria unto death, the truest communion possible with Christ who shed his Blood, and by that sacrifice brings near those who once were far off (cf. Eph 2:13).

While for all Christian communities the martyrs are the proof of the power of grace, they are not the only ones to bear witness to that power. Albeit in an invisible way, the communion between our Communities, even if still incomplete, is truly and solidly grounded in the full communion of the Saints—those who, at the end of a life faithful to grace, are in communion with Christ in glory. These Saints come from all the Churches and Ecclesial Communities which gave them entrance into the communion of salvation.

When we speak of a common heritage, we must acknowledge as part of it not only the institutions, rites, means of salvation and the traditions which all the communities have preserved and by which they have been shaped, but first and foremost this reality of holiness.¹³⁹

In the radiance of the "heritage of the saints" belonging to all Communities, the "dialogue of conversion" towards full and visible unity thus appears as a source of hope. This universal presence of the Saints is in fact a proof of the transcendent power of the Spirit. It is the sign and proof of God's victory over the forces of evil which divide humanity. As the liturgies sing: "You are glorified in your Saints, for their glory is the crowning of your gifts".¹⁴⁰

Where there is a sincere desire to follow Christ, the Spirit is often able to pour out his grace in extraordinary ways. The experience of ecumenism has enabled us to understand this better. If, in the interior spiritual space described above, Communities are able truly to "be converted" to the quest for full and visible communion, God will do for them what he did for their Saints. He will overcome the obstacles inherited from the past and will lead Communities along his paths to where he wills: to the visible koinonia which is both praise of his glory and service of his plan of salvation.

85. Since God in his infinite mercy can always bring good even out of situations which are an offence to his plan, we can discover that the Spirit has allowed conflicts to serve in some circumstances to make explicit certain aspects of the Christian vocation, as happens in the lives of the Saints. In spite of fragmentation, which is an evil from which we need to be healed, there has resulted a kind of rich bestowal of grace which is meant to embellish the koinonia. God's grace will be with all those who, following the example of the Saints, commit themselves to meeting its demands. How can we hesitate to be converted to the Father's expectations? He is with us.
