Donate Where the need is greatest Donate Fundraise When you donate to ‘Where the need is greatest’, Missio can direct your gift to wherever it will have the biggest impact right now. That might include helping local missionaries overseas, training future Priests and Sisters and giving hope to the world’s poorest children through practical and spiritual help. Missio works through the Catholic Church directly with local Bishops in mission dioceses. This means that you can trust that your gift is distributed promptly and efficiently where the need is greatest.
