Once a person believes...he is saved.

Lutero said:

Once a person believes, the grace is received by them, he is saved.
Please show a verse where it says that [He, who is not baptized shall be damned] 

Why? Did I say that?

In case, he had the DESIRE in his heart to go to a church to get baptized after believing, but dies in an accident on the way to the church, will he be sent to hell?

I believe you are making a reference to Baptism of desire.

Yes, but there are verses where I see that the Holy Spirit came on people prior to baptism. Are you ignoring these verses?

No. What you are ignoring is this. 

Jesus tied Baptism of the Holy Spirit, to Baptism of water (John 3:5). That means that if you believe and are baptized, you will receive the Holy Spirit (Acts 2:38).

Jesus also said that the Spirit blows where it will (John 3:8). And that many who call Jesus, Lord, will not be saved (Matt 7:21). That means that many who claim to have faith, will not necessarily be baptized of the Holy Spirit. Because the Spirit of God blows where it will. If you want to guarantee that you have been baptized by the Holy Spirit, you need to the Baptism of Jesus Christ, which is the Baptism of water.

According to you, salvation is a grace, then it is received through faith.
Ephesians 2:8
For by grace you have been saved through faith; and that not of yourselves, it is the gift of God;

Perhaps, but Scripture doesn't define that. I think you did.

Are you saying that salvation is not a grace?
Titus 2:11
King James Version (KJV)
11 For the grace of God that bringeth salvation hath appeared to all men,

Where is the word "grace" here? Nothing in the context of the verse indicates they received grace.

Perhaps, but Scripture doesn't define that. I think you did. Nothing in the context of the verse indicates grace is received.

Scripture says that grace is received through faith. Nothing else.

Faith is expressed in obedience to God:
Romans 16:26
King James Version (KJV)
26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:

It is doubtful that any disobedient person has any faith towards God.

That's nice, but unfortunately, the Priests and Bishops never receive any grace through the sacrament of matrimony.  And a member of a Catholic Parish cannot receive the Sacrament of Holy Orders.

Because you say so? I believe the Church which Scripture calls the pillar of truth (1 Tim 3:15).

So in all, no one in the RCC can generally receive all the seven sacraments, but I know one person who was able to do that. He had a family, when his wife died, he became a catholic priest (as all his kids were grown up and married).

It is not required that one receive all seven of the Sacraments. If that were so, then everyone would be a ministerial priest. Yet, God gave us all different roles to play in His Church.

Sincerely,

De Maria
