What would be necessary is to:
1) deny your own denomination;
2) deny your demoniantional patriarchal head in favour to that of the papacy;
3) forget about the denominational blood of the martyrs in Christ;
4) forget about the 500-2000 year history of denomination's history in preaching the gospel;
5) accept to be assimilated into a different denomination than that you had been brought up in;
6) accept the RCC as your new denomination now and forever;
7) accept pope infalibility;
8) enjoy second class citizenship in your new joined religious institution;
9) forget about your culture/tradition that your denomination means to you.
10) accept dictation from the the superior one.
I have just covered some aspects of what is required to join RCC, other than that, why not! let
1. In some sense, you don't have to deny that there may exist good decent faithful in the previous denomination, but you have to deny their teachings as false and heretical to some extent, that's a given.
2. Yes of course, if not you wouldn't have a desire to become Catholic to begin with.
Either you believe that the pope is the successor of Saint Peter, the supreme leader of Christ's only church, the church created by Christ himself where any other self proclaimed church are founded by men or you don't.
If you don't, why on earth will you become catholic to begin with?
Catch my drift?
3. To say that one has to forget about the blood shedded by the denomination one leaves is absurd.
Why does one have to forget about the martyrs of one's previous denomination just because one think their religious leaders erred in one or several dogmatical matters?
Their faith would most likely have been great if they chose to die for Christ.
I consider Christians who have suffered martyrdom for their faith to be witnesses to all of us.
If a Lutheran brother die for his faith who am I to ridicule that enormous offering?
I personally mourn over every brother or sister who are killed for our Lord.
To have full deposit of faith is a tremendous advantage and treasure that we catholics have been blessed with, but it doesn't give us the authority to judge anyone.
Our separated brethren outside the church has a disadvantage and for them separated by the Holy Mother Church to suffer martyrdom is in a sense even greater than for us catholics to die for our faith as I consider people without the full deposit of faith to start their faith journey with a handicap.
So again I disagree with you in your perception.
4. Again if one has come to see the truth of the church and believes that even the purest and modest of denominations are separated from THE ONE church established by our Lord and that they are contradictions of what Christ himself intended as he established the church, I don't think the traditions of the heterodox denomination matters to much anymore.
One does not have to hate his or hers origins to think that they are lost, cut of from the tree.
I am a former Lutheran myself, do I consider Luther to be a heretic, yes.
Do I consider Lutheranism heresy, yes.
Does this mean that I don't see any good things in Lutheranism? No.
In some ways I'm even grateful for being born into that faith.
It is in the Lutheran church that I was baptized and presented to Christ.
I learned to pray, I learned lots of stuff that I cherish greatly to this very day.
I even see Lutheranism as the start of my path back home to the Catholic faith, yes I say home because I consider Catholicism to be Christianity as it's ment to be.
God works in mysterious ways you know...
5. You mean to be a part of God's wonderful quire that together are blessed with a unison voice to worship Christ with the saints and Mother Mary for eternity?
Expression is a key factor here.
If one believes the church to be the one, one shouldn't see this as negative at all.
6. Consecrate yourself to Christ and his church for now and forever, YES, YES AND YES.
Why would one need to relocate?
Isn't peace found in him alone?
Why would his body, the church stick out as anything different than himself the head?
7. The church is infallible, why? Because Christ said so.
"The gated of hell shall not prevail against it".
A gathered council affirmed what the church herself always have taught, that The Holy See of Saint Peter are the primacy and supreme leader of the church.
Christ gave Saint Peter the authority to bind and loose which is exactly what the pope does.
That's why a individual who convert to Catholicism gladly obey the Papal office.
(A side note in all of this is that the pope is a servant of Christ.
The Pope is the protector of the Gospel and the church nothing else.
As JPII said it so famously regarding ordination of female clergy, "I would if I could, but I can't because I'm only pope")
8. Sorry if I sound rude, but this is as far as it's possible to come from the truth.
This has no grounds what so ever.
Being a convert myself I was appreciated, accepted and welcomed from the moment I walked into the church.
I've always been treated as if Im a lifelong catholic both before my actual conversion and afterwards.
There are absolutely no second class citizenship at all and to be honest I find it a tad insulting that you imply that I am such.
This is unofficially aswell as officially the case.
We even believe that all baptized Christians after the trinitarian formula are in half communion with our church.
It's like a child are being baptized into the catholic faith, but raised into another faith tradition as soon as the baptismal ritual are over.
So for any christian to convert to Catholicism is to come back home as we see it.
Why should a lost son or daughter who turn home to their father be considered a second class citizen?
Difficult to understand the reasoning behind that conclusion...
9. I'm not sure I understand you correctly but if you're say episcopal Christian, confessional Lutheran or any other western high church Christian there are very little difference between mass and the service you're used to.
Again, the history of your previous denomination will be seen as a history of disobedience and rebellion towards Rome and Christ (or a result of such) when one comes to realize the truth that rests within the Catholic faith.
10. There are no room for dictation, but rather unity under the Holy See.
Some popes have been dictating and horribly so in the past, but one has to remember that even the supreme poniff is just a human.
The past is both glorious as well as grusome.
Unrighteousness has been committed by popes and bad men, but never by the church.
The Divine truth of the faith had never been shattered by the evilness of some men and an era that didn't knew the moral standards that we've been blessed with after WW2 (despite abortion and other evilness that is).
So see the protection of the divine truth that are still within and use that to praise God for his church and his servants the Popes.
