N.B.: The Vatican has not confirmed it, or announced it, but Fr. James Martin posted the news on social media a short time ago, citing an Italian news agency.
The Catholic Herald in the UK has this:
Blessed Mother Teresa of Calcutta will be canonized on Sunday September 5 according to the news agency, Agi. Catholic News Service have reported that a panel of doctors have concluded that there is no natural medical explanation for the miracle attributed to Mother Teresa’s intercession. This means that her cause will now be examined by a panel of theologians before being assessed and voted upon again by a panel of cardinals with the final decision resting with the Pope. The Vatican has not yet confirmed the report. September 5 falls within the Year of Mercy and also marks the anniversary of Mother Teresa’s death.
I’d advise caution with these widely-circulating reports. The Herald story gives the distinct impression this is not a done deal and Pope Francis still needs to sign off on this.
UPDATE: More details from theAP:
A Vatican official says it’s too soon to say if Mother Teresa will be made a saint during the 2016 Holy Year of Mercy. There’s been speculation the nun who worked with the destitute and dying in India would be made saint by Pope Francis in a ceremony during the Holy Year, which runs from Dec. 8 till Nov. 20, 2016. The Italian bishops conference daily Avvenire on Wednesday, citing Italian news agency AGI, called Sept. 4 a “probable” date. Vatican spokesman the Rev. Federico Lombardi stressed that Francis still needs to approve a miracle attributed to Mother Teresa’s intercession before she can become a saint.
