About Catholic Saints

Catholic saints, including St. Cosmas, are Christians whom the Catholic Church has formally recognized as having lived lifes of heroic holiness and who now dwell with God in heaven, offering an example of faith for those still on their earthly journey. Catholics don't worship saints, but ask them to pray to God with us and for us — much as one might ask a trusted friend to pray for them — trusting that those closest to God can join their voices to ours before Him.
