What is the sacrament that nourishes and strengthens the christian community?

Roman Catholic AnswerAll the sacraments nourish your faith, but the two sacraments that we repeat most frequently: confession and the Eucharist both nourish our faith the most, and, far and away is the Most Holy Eucharist, which is more than a Sacrament, it is the actual Body and Blood of Our Blessed Lord, so it is not just His Body and Blood, but His Soul and Divinity as well. All sacraments give you grace, and those you repeat most often are bountiful sources of that grace, but Our Blessed Lord is, Himself, the Source of all grace.
