Orthodox Catechism Questions 74&75

Our Sunday school lesson for today. Be blessed.

How are you admonished and assured in baptism that you are a partaker of the only sacrifice of Christ? Because Christ commanded the outward washing of water, joining this promise to it, that I am no less assuredly washed by His blood and Spirit from all uncleanness of my soul, that is, from all my sins, than I am washed outwardly from the filthiness of the body with water. —Q74, An Orthodox Catechism
What is it to be washed with the blood and Spirit of Christ? It is to receive of God forgiveness of sins freely, for the blood of Christ which He shed for us in His sacrifice upon the cross and also to be renewed by the Holy Spirit, and through His sanctifying of us to become members of Christ, that we may more and more die to sin, and live holy and without blame. —Q75, An Orthodox Catechism
