I have heard this all my life and watching society all those years I conclude that priests want to control your life and mine with garbage rhetoric swallowed by the masses much to the delight of the upper classes who certainly don't behave in a like manner.
They can speak all they want, but if they are not living it then it's nothing! How can people tell others how to live if they are not living it themselves. Those who do so are hypocrites!
And I'm not talking about just the priests, but everyone, do they live like Jesus? Can you see the heart of Christ in them? If any of them do, then they are living right before God. Whatever the denomination. It's not the denomination, it's the life and the heart of the person. And all those who belong to Christ will have his heart and you will see his life and God's love, in and through them. They are Gods true people. All these denominations are made by man, Jesus isn't a denomination, he's the way and his way is the true way to follow. And those following him will be denying themselves, and they will bare their cross, turning from the world and works of the flesh to live by the will of God. And in doing so they glorify God and Christ.
So it doesn't matter what they say, people are great with words, but if they don't live right right before God then it's nothing. It's in the life and the word. It's no good knowing all the scriptures if we love our flesh before God. God wants our hearts and minds and we should be thinking of how to please him daily putting ourselves last. And caring for those we see in need in our daily life because the life of Christ is in us and he cared for everyone.
If there's no love and care there, then there's no life there! Words without the life mean nothing, as James said, I'll show you my faith by works.
Matthew 15
Ye hypocrites, well did Esaias prophesy of you, saying, This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me. But in vain they do worship me, teaching for doctrines the commandments of men.
Colossians 3
And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.
