I am happy for you...its God's grace that is calling you and you are responding to His Call...to begin on the path to RCIA...and to enter His Church. I admire your courage and your truthfulness (two traits that will make your journey into and in the Church as a member in full communion...a real journey of peace)...do not be afraid of the truth..it is true that the Truth will set you free...because the Truth is not something...it is someone...a person...Our Lord Jesus Christ.
John 14:6 RSV-CE)6** Jesus said** to him, "I am the way, and the truth, and the life; no one comes to the Father, but by me.
Two points...for your consideration:
1...meeting with a priest and discussing your personal situation and your spiritual situation is the second best thing that you can do...and are doing.
2....the first best thing you can do is to focus intently on the Sacred Heart of Divine Mercy of Our Lord Jesus Christ...make this your number one focus and priority each day of this part of your journey...He holds nothing against you and wants to welcome you into the Body of Christ...His Church...("...He takes nothing away from you and gives you everything...". Pope Benedict XVI Inaugural Homily April 2005).-the first thing that Our Lord Jesus wants to do is free you from the past and anything that may not have been in accordance with God's Law...as taught by the Magisterium of His Church...so maybe something was not quite right in your past...maybe is was even sinful...maybe a serious sin...pray/talk with the Lord about it...discuss it with his priest...confess it when the time arrives for your first Sacrament of Confession...and be set free! Also...all along the way of this new journey...realize very vividly...that the Lord is smiling at you...because you are answering His very specific call (His graces-His gifts) to bring you out of the past and free you...
Now...because you asked...re: sterilization
Catechism of the Catholic Chruch (CCC)[INDENT]2399 **The regulation of births represents one of the aspects of responsible fatherhood and motherhood. **Legitimate intentions on the part of the spouses do not justify recourse to morally unacceptable means (for example, direct sterilization or contraception).
[/INDENT]...but, remember that this is exactly what and why your priest (the priesthood)...acting in the person of Christ (in persona Christi)...is trained to minister and discuss with you in a pastoral way to resolve this...with you and Our Lord and His Church (remember...that everything that we do "good or bad"...affects not just us in our relationship with the Lord...but also and just as importantly...the Body of Christ...the Church). The priest's spiritual guidance will help you to resolve any issues...in your own conscience...and if needed...offer you the Sacrament of Confession/Reconciliation/Penance...when the time is right in RCIA.
Lastly...God bless you on your journey...be not afraid...just smile knowing that the Lord Jesus has taken a very special interest in you and your journey!...and so have we!
