I love my Church and have no intention of leaving it.
Fortunately not all Catholics think the same way on everything.
I first learned that Jesus had brothers and sisters in a Bible Study class taught by a Catholic priest.
I agree with nearly all of what the Church teaches.
Some policies are not etched in stone and are subject to change as the Pope indicated in the article above.
The perpetual virginity of the Blessed Mother is one of those things carved in stone. It is unalterable fact. If you wish, you may adhere to a theory that the “brothers and sisters” of Jesus are half-siblings, from a (hypothetical) previous marriage of Joseph. It’s not a well-founded theory however, in view of Biblical testimony to the names of both parents of the “brothers” of Jesus.
BTW, did the learned Catholic priest who taught you these heresies teach you also that ancient Aramaic refers to remote male relatives as “brother” because it has no word for cousin?
Finally, you do not understand what the term Immaculate Conception means. You should. It’s important.
The problem is that most Americans, most Westerners believe that the Church is a democracy.
That is wrong, and it comes from following and not thinking.
We do not get to opine about the Church.
When we do, it is pride. People are fooled into believing that they get to say what truth is.
That’s Relativism. And it’s a heresy.
We do get to say and believe whatever we want, but not without consequences.
People who want to believe what some heretical clergy member told them, and will completely disregard all the energy they could be otherwise spending finding out what the Church states about things, will not read the Catechism.
Stating that they are too sure of their own thinking.
But this is what Eve did. God told her what not to do, same as her following husband/mate. They each said someone else told them it was okay, disregarding the law.
Set forth by the Creator.
That is pride. And it is a deadly sin.
So, fi people want to say they have an opinion about what the Church says, they don’t have to be Catholic.
But when they do so and state they are Catholic, and a LOT of people do this, then others will be swayed. There is nothing quite so attractive and powerful as a dissenting Catholic.
Okay, I’ll cut and paste the Catechism, as it is too painful for some people to crack the book, or click on sites I’ve included, though, I know it won’t be read.
Mary - “ever-virgin”
499 The deepening of faith in the virginal motherhood led the Church to confess Mary’s real and perpetual virginity even in the act of giving birth to the Son of God made man.154 In fact, Christ’s birth “did not diminish his mother’s virginal integrity but sanctified it.”155 And so the liturgy of the Church celebrates Mary as Aeiparthenos, the “Ever-virgin”.156
500 Against this doctrine the objection is sometimes raised that the Bible mentions brothers and sisters of Jesus.157 The Church has always understood these passages as not referring to other children of the Virgin Mary. In fact James and Joseph, “brothers of Jesus”, are the sons of another Mary, a disciple of Christ, whom St. Matthew significantly calls “the other Mary”.158 They are close relations of Jesus, according to an Old Testament expression.159
501 Jesus is Mary’s only son, but her spiritual motherhood extends to all men whom indeed he came to save: “The Son whom she brought forth is he whom God placed as the first-born among many brethren, that is, the faithful in whose generation and formation she co-operates with a mother’s love.”160
“Fortunately not all Catholics think the same way on everything.”
All practicing Catholics believe in all the tenets of the Church.
What you mean is that not all people who say they are Catholics believe in what the Church says.
You might add how you think that is a good thing.
