Dear Roy,

Thanks for the good question.

I'd like to address your question and another question.

You said:

• If you desired to be God would He forgive you?

Yes! He would, if you understood it was a grave sin against the First Commandment.

I am the LORD your God, who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before me.

There is never a sin that is so grievous for which God will not forgive us, except one.
When we say:

My sin is so great, God will never forgive me, so I won't ask for His Forgiveness.

This is the sin against the Holy Spirit talked about by Our Lord in Matthew's Gospel.

At the root of this sin is pride and a lack of humility.

This is a grave sin, but for the Catholic, the powerful sacrament of Confession is there to heal us and make us new again every Saturday afternoon.

Although a non-Catholic cannot receive sacramental Confession, I would recommend they visit or talk with a priest if this is a sin they struggle with and ask for guidance.

As my colleague Eric put it so well:

Remember that the Confessional is a tribunal of mercy and healing, not of judgment. The point is not to accuse you or impose guilt; the point is to relieve guilt and apply the balm of mercy to sins so that [you] might be healed.

A sin is like an injury, and the priest is like a doctor.

If you had asked:

• If you desired to be God-like would He forgive you?
  

I would say being God-like is not a sin. All mankind is called to partake in the work of the Body of Christ, by grace alone. That's what is so great about Christianity. Jesus, by His own choice, wants us to assist in the salvation and redemption of mankind. No one is undermining the sole mediation of Jesus. Why? Because, through our baptism, we are In Christ, and our good works are His good works.

Christians are called to be a holy people. Holy means "to be set apart" from the others for the work of God.

I hope this helps,

Mike
