I would encourage you to do your own homework and rely less on Catholic blogs.
Why should I. What you fail to see Maj1, is that being in full communion with or Catholic faith is a beautiful thing. Unfortunately for you and our other separated brethren, being in full communion with the thousands of other Protestant sects is next to impossible. Too many different beliefs and practices. In other words...Dis-unity.
Your friend's blog stated concerning Ezekiel 9:4 that a mark thou tau on the foreheads," etc. St. Jerome and many others have thought that the letter tau was that which was ordered to be placed on the foreheads of those mourners; and Jerome says, that this Hebrew letter ת tau was formerly written like a cross.
While All this is true in itself, but it is not true in respect to this place in Ezekiel 9.
By what authority can you say it's not true? Are you suggesting your understanding/interpretation of this passage is correct, (absolute and without error) and his is not?
My dear friend..........there are NO Biblical roots, or instructions or suggestions that tell us to cross ourselves.
I disagree, for there is compelling biblical evidence that supports this practice. For example.
Rev. 7:2-4; 14:1 and 22:4. Many Catholic Theologians have traditionally associated the seal on the foreheads of the servants of God with the Sign of the Cross. I know you will probably disagree with them, so before you do, please show by what authority you have to do so.
The idea of a sign or a seal marking members of the Church as God’s own also surfaces elsewhere in the New Testament. In 2 Corinthians 1:22, Paul writes that, “the one who gives us security with you in Christ and who anointed us is God; he has also put his seal upon us and given the Spirit in our hearts as a first installment.” Similar language is used in Ephesians 1:13 and 4:30, in which Paul talks about how Christians have been “sealed” with the Holy Spirit.
This is a practice that is not found in the Bible either.
Once again, your unbiblical adherence to sola scripture does not apply to the Catholic faith. Not to mention the Protestant practices of the altar call, the sinner's prayer, ect. are not found in the bible either. Then have you forgotten the passages.....Jn.20:30-31?
"Many other signs also did Jesus in the sight of his disciples, which are not written in this book. But these are written, that you may believe that Jesus is the Christ, the Son of God: and that believing, you may have life in his name."
Are you saying Maj1 that anything Jesus did or said that didn't make it into the books of Scripture are false and should not be adhered to? I think not!
Jesus never crossed Himself, nor did the apostles, nor should we.
How do you know this? You being a sola scripturists, please show in Scripture where it say's this. Now if I was to choose between you belief in this or the early Church fathers that were only a generation or two from Christ and the apostles, that would be a no-brainer. Lets take a look:
The early Christian apologist Tertullian wrote, "In all our travels and movements, in all our coming in and going out, in putting on our shoes, at the bath, at the table, in lighting our candles, in lying down, in sitting down, whatever employment occupies us, we mark our forehead with the sign of the cross."
Athanasius, the great bishop of Alexandria who almost single-handedly stood for Christian orthodoxy against the powerful Arian heresy, taught his flock that "by the sign of the cross...all magic is stayed, all sorcery confounded, all the idols are abandoned and deserted, and all senseless pleasure ceases, as the eye of faith looks up from Earth to heaven."
Cyril of Jerusalem echoed Tertullian as he encouraged the Church: "Let us not be ashamed to confess the Crucified. Let the cross, as our seal, be boldly made with our fingers upon our brow and on all occasions over the bread we eat, over the cups we drink, in our comings and in our goings, before sleep, on lying down and rising up, when we are on the way and when we are still."
The great bishop of Cappadocia, Basil, taught that the sign of the cross was a tradition the originated with the apostles, "who taught us to mark with the sign of the cross those who put their hope in the name of the Lord."
Even Martin Luther urged his followers to use the sign. In his Catechism of 1529 he instructed fathers to teach their households the following: "In the morning, when you rise from bed, sign yourself with the holy cross and say, 'In the name of the Father, the Son, and the Holy Spirit. Amen.'...At night, when you go to bed, sign yourself with the holy cross and say, 'In the name of the Father, the Son, and the Holy Spirit. Amen.'"
The Christian who rejects the sign of the cross is rebelling against his own roots and is guilty of what C. S. Lewis called "chronological snobbery" about the superiority of modern thinking. Instead we should learn from our fathers, thereby heeding the wisdom of Bernard of Chartres, who recognized that the history of the Church Church enables us to be "dwarfs standing on the shoulders of giants."
