Christians on both sides (Catholic and Protestant) forget that both sides share the core believes found in both the apostles creed and nicene creed.
For example:
The Nicene Creed states:
We believe in one God,
the Father, the Almighty,
maker of heaven and earth,
of all that is, seen and unseen.
We believe in one Lord, Jesus Christ,
the only Son of God,
eternally begotten of the Father,
God from God, light from light,
true God from true God,
begotten, not made,
of one Being with the Father;
through him all things were made.
For us and for our salvation
he came down from heaven,
was incarnate of the Holy Spirit and the Virgin Mary
and became truly human.
For our sake he was crucified under Pontius Pilate;
he suffered death and was buried.
On the third day he rose again
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.
We 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 worshiped and glorified,
who has spoken through the prophets.
We believe in one holy catholic and apostolic Church.
We acknowledge one baptism for the forgiveness of sins.
We look for the resurrection of the dead,
and the life of the world to come. Amen.
All of these statements unify us as Christians, as brothers and sisters of Christ.
I don’t think there is anything wrong with the Protestant Church it’s awesome. I used to be Protestant and it has a very special place in my heart. It has its quirks and it certainly isn’t perfect but if a person for whatever reason doesn’t agree with the Catholic teaching it is a good place to go.
Be aware: because the Protestant Church is also Christian: most denominations especially the Evangelical ones are extremely: prolife, teach sex after marriage, the importance praying regularly, reading the bible, attending church regularly and more. The main difference is the belief in the Eucharist, the saints and a few other things that are best left for another discussion. BTW the Protestant Church has 5 or 6 less sacraments: for example most only recognize baptism and not the rest.
