Quite often the differences to Baptists and Reformed are discussed when it comes to Baptism. What are the differences between Lutherans and Catholics concerning Baptism? Are these differences less discussed because they are less important?
While there are similarities between Lutherans and Roman Catholics in the outward administration of baptism (using water in the name of the Triune God, baptizing infants, baptizing only one time in life), there are significant differences.
The Roman Catholic Church teaches that baptism, in forgiving original sin, removes the sinful nature, and provides forgiveness only for those sins that were committed prior to baptism. In addition, the Roman Catholic Church teaches that baptism gives individuals the power to cooperate with God in their salvation.
You can read explanations on these and other differences in A Lutheran Looks at Catholics.
As far as how frequently these differences are discussed compared to the differences of Baptists and the Reformed, context is always important. These differences will be discussed as individuals like you request the topic to be addressed or as circumstances warrant.
We can be thankful that God provides baptism to wash away our sins, to deliver us from death and the power of the devil, and to offer and give us eternal life (Acts 2:38; Acts 22:16; Romans 6:3; Hebrews 2:14-15; 1 Peter 3:20-21).
