one God who gave us the priesthood .... obedience is key
Oh, my goodness, Mormons say the same thing! Matt has a chart that shows the similarities between the RCC and LDS Church--and here are 2 more!
ALL Christians are a royal priesthood to God our Father, with Jesus Christ as our great High Priest. No need for some formal, elitist priesthood, when each and every believer is a priest!
Obedience may be the key in your church--and the LDS--but Grace is the keyword to us born-gain Christians. God's grace--His undeserved love--is the very foundation of Christian beliefs, for "while we were STILL sinners, Christ died for us" and "He saved us, NOT on account of works we have done in righteousness, but on account if His mercy."
God saves us on account of Jesus Christ and what He did for us on the cross. That is pure grace--which is ours because Christ was fully obedient, in our stead, even to death on the cross.
