The Power of the Cross failed? You can't be serious, Paul!
You suppose the cross defeated Jesus?

I know He rose again.
By the power of God in heaven, Jesus was not subject to the power of the cross.

Whom God hath raised up, having loosed the pains of death:
because it was not possible that He should be holden of it.

Acts 2:24
 It's through the Power of Cross we enter Heaven!
So Christians say,
who refuse to do the law.

I rather believe what God's word says.
Knowing that crucifixes are murder weapons.

All the commandments which I command thee this day
shall ye observe to do,
that ye may live,
and multiply,
and go in and possess the land
which the LORD sware unto your fathers.

Deuteronomy 8:1

You know NOT what you speak!
I show you what God said, from the holy Bible.

Why don't you believe in, and offer up the unleavened bread?
Even because you rather believe upon the cross, than do what Jesus said.

Thou shalt not offer the blood of My sacrifice with leavened bread;
neither shall the fat of My sacrifice remain until the morning.

Exodus 23:18

You can quote Scripture all you like, Paul, but it doesn't mean you understand it!
I know.
Only those that eat the bread of Catholicism understand it fully.

Unfortunately for you, God's word says not to eat the fat of their beasts
(and you are too busy offering up their beasts, to consider God's words).
And now I see there are a whole lot of posts,
with Catholic interpretations,
all put to justify cross worship.

Thou shalt not offer the blood of My sacrifice with leaven;
neither shall the sacrifice of the feast of the passover be left unto the morning.

Exodus 34:25

Jesus is the Word is the Lord. Heart Throb
And Jesus is the Saviour, not the cross He was so brutally hung upon.
So don't worship the instrument that wicked men tried to kill Him with.
Don't believe the wicked men that direct you to worship Jesus like that.
Offer up His body instead, to teach the commandments, as Jesus said
`Paul

Wherefore lay apart all filthiness and superfluity of naughtiness, 
and receive with meekness the engrafted word, which is able to save your souls.
James 1:21
