Pope Francis urged bishops on Monday to speak their minds without fear about contentious issues like contraception, homosexuality, marriage and divorce at the start of a two-week meeting aimed at making the church's teaching on family matters relevant to today's Catholics.
Francis told bishops they shouldn't even be afraid of showing him disrespect, saying he wants a frank debate that shouldn't be tempered by fears that some issues are too taboo to even be discussed.
"You have to say what you feel the Lord tells you to say, without concerns of human respect and without fear," Francis instructed the bishops at the start of their meeting.
At the same time, he urged the nearly 200 cardinals, bishops and priests gathered for the synod to listen to one another with humility "and welcome with an open heart what our brothers say."
The run-up to the meeting has been marked by mudslinging between conservative and progressive clerics over issues such as whether Catholics who divorce and remarry without an annulment can receive Communion. Church teaching says such Catholics are living in sin and cannot receive the sacraments.
While insisting he is a "son of the church," Francis has said the church must show more mercy and be a "field hospital" for wounded souls, suggesting he is seeking some sort of accommodation that conservatives say simply does not exist.
In a bid to encourage free-wheeling debate, the Vatican is restricting public information about what is said behind closed doors during the synod, not releasing texts of individual bishops as it has done in the past.
In a measure to inform the debate, Francis decided last year to send a 39-point questionnaire to bishops' conferences around the world, seeking input from ordinary Catholics about their acceptance of church teaching on a host of issues related to Catholic family life.
The surveys confirmed that while most Catholics believe in the indissolubility of marriage, the vast majority of Catholics ignore and reject church teaching on sex and contraception. The responses also said the church must develop a pastoral plan to minister to gays and lesbians in civil unions and to children being raised in such families, making the synod the first time the Vatican is addressing homosexuality on a pastoral level.
Church reform groups have said such honest responses, and the Pope's insistence that no issue is too taboo to be discussed, are reason for hope. Conservative clerics, however, are hoping that the synod will simply reaffirm church doctrine and make it more known and understood by Catholics.
A top synod official, Cardinal Peter Erdo of Hungary, suggested that one answer to the problem of divorced and remarried Catholics was to simplify the annulment process. That way, he said, divorcing couples could better know how marriages can be annulled since "it does not seem hazardous … to believe that many marriages celebrated in the church may be invalid."
In fact, Francis has quoted a former archbishop of Buenos Aires as saying half the marriages celebrated in the church are invalid, primarily because the bride and groom didn't fully know what they were getting into or appreciate that marriage is a life-long commitment.
Erdo said doctrine was not up for debate but that the church must better discern pastoral responses on a case by case basis.
