I remember when I was a kid, I had a friend who would play chess with 4 or 5 people at the same time. It boggles my mind and I must confess I do not possess this talent to address many scriptures put forward. Before we go forward, can we take a step backwards and ascertain an understanding of points of faith.
Sure.
Heb 4:14 Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession.
Heb 4:15 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
Heb 4:16 Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
If Jesus is the mediator and high priest, the scripture states clearly that we may (by no other means than by the mediation of Jesus, our High Priest and mediator) come before the throne of grace, boldly might I add and obtain mercy and find grace from God our Father.
That is a misunderstanding which Protestants have of that Scripture.
Scripture does not contradict itself.
1st. Scripture tells us to mediate for our fellow man in many places. But, although, only one is necessary in order to prove your understanding wrong, I will provide three:
1 Timothy 4:16
Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.
James 5:20
Let him know, that he which converteth the sinner from the error of his way shall save a soul from death, and shall hide a multitude of sins.
1 Timothy 2:1
I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men;
If that is the case then, that we must all make intercessions for all mankind, then we are all mediators.
Hebrews 7:25
Wherefore he is able also to save them to the uttermost that come unto God by him,
seeing he ever liveth to make intercession for them.
2nd. So, why is Christ called the sole Mediator? Because it is Christ who mediated the New Testament.
Listen to the Word of God:
Galatians 3:18-20
King James Version (KJV)
18 For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise.
19 Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.
20 Now a mediator is not a mediator of one, but God is one.
Who mediated the Law? Who mediated the Old Testament? It was Moses. This verse is about Moses mediating the Old Testament. And it is comparing Moses, the sole mediator of the Old Testament to Jesus, the Sole Mediator of the New.
20 Now a mediator is not a mediator of one, but God is one.
21 Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law.
22 But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.
Hebrews 8:5-7
King James Version (KJV)
5 Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount.
6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
7 For if that first covenant had been faultless, then should no place have been sought for the second.
To conclude, if you pray for anyone else, then you are mediating between them and God. And by your actions you are contradicting your professed belief that Christ is the Sole Mediator in every respect.
Sincerely,
De Maria
