Then, Benedict XVI invited "the pastors and devotees to take renewed care of the preparation of the Eucharist". "We must do everything in our power to receive it in a pure heart", pursuing "a purity untouched by sin through the Sacrament of forgiveness". In his message to the Eucharistic Congress, the Pontiff mentioned that "sin, especially major sin, weakens the action of the Eucharistic grace in us". Those people who "cannot receive Holy Communion because of their situation explained the Holy Father will find in spiritual communion and in the attendance of Mass a saving strength and effectiveness". Then, in his message, the Pope explained that "for God’s people to always have its ministers", "we must ask the Lord to give new priests to His Church. So I ask you to pass this appeal to priesthood down to the young men, so that they will accept, with joy and without fear, to answer God". May the families, highlighted the Pontiff, "be the primeval place and the cradle of callings". Finally, Benedict XVI announced that the next Eucharistic Congress will be held in Dublin, Ireland, in 2012.
