Words have differing meanings to different people.
Example - Grace.
For a Lutheran, grace is understood to be God's favor and forgiveness towards a person, given to them on account of the death and resurrection of Christ Jesus.
For Rome, Grace is a gift of God, freely given, that provides a person energy and strength for living a proper life, whereby one may obtain salvation through remission of sin and the exercise of merit.
Both can say that we are saved by grace.... One views grace as bringing Christ to us and thus bring salvation to us. The other views grace as the spiritual gas in our cars that let us drive to Christ and reach the goal of salvation.
