I edited it for other reasons than that.
Ok, I will address the question to you. Are able to accept that there can be valid moral belief systems other than the one you must believe as a Catholic? Note I am not suggesting in any way or form that a yes answer means that you give up your own beliefs.
Its a simple question that you can answer with a yes or no.
Of course we believe the Catholic Church is the culmination of all belief systems and as such is the closest to the Truth as God has allowed. Any Catholic who says otherwise does not accept Catholic doctrine:
Nicene Creed.
I believe in
one God,
the Father almighty,
maker of heaven and earth,
of all things visible and invisible.
I believe in
one Lord Jesus Christ,
the
Only Begotten Son of God,
born of the Father before all ages.
God from God, Light from Light,
true God from true God,
begotten, not made, consubstantial with the Father;
through him all things were made.
For us men and for our salvation
he came down from heaven,
and by the Holy Spirit was incarnate of the Virgin Mary,
and became man.
For our sake he was crucified under Pontius Pilate,
he suffered death and was buried,
and rose again on the third day
in accordance with the Scriptures.
He ascended into heaven
and is seated at the right hand of the Father.
He will come again in glory
to judge the living and the dead
and his kingdom will have no end.
**
I believe in the Holy Spirit, the Lord, the giver of life,
who proceeds from the Father and the Son,**
who with the Father and the Son is adored and glorified,
who has spoken through the prophets.
I believe in one, holy, catholic and apostolic Church.
I confess one Baptism for the forgiveness of sins
and I look forward to the resurrection of the dead
and the life of the world to come. Amen.
