A great Catholic Bible and Catechetical Downloadable Study Software Program, and best of all its Free.   

From:  http://www.esnips.com/web/CatholicApolegetics
These are all eSword modules-Bibles, Commentaries, Dictionaries, and Topical all  for the eSword base Bible software program..  All to help Catholics and those interested in knowing more or understanding what the Catholic Church truly teaches and why. All modules are free as well as the Base esword program for download.

The Base progam is a free download at:

Rick Myers e-sword site states: e-Sword is a fast and effective way to study the Bible.  E-Sword is feature rich and user friendly with more capabilities than you would expect in a free software package. The fact that e-Sword is free is just one of the blessings and does not speak of the quality of the software. I make my living writing software and I believe I have put forth my best effort in this endeavor. The real work, however, was put in by the godly men and women who devoted countless years creating the texts that have been made available for our benefit. (From the e-sword Web site Rick Myers)

The Program has the ability to accept user created modules hence a substantial number of user Catholic modules including the Early Teachings of the Church in the first few centuries (a must read), Haydock Commentary, The Great Cornelius Lapide commentary, A Catholic Commentary on Holy Scripture, St Thomas works in the Catena commentary on Gospels by early church fathers, and his Summa Theologica, The Douay Rheims Catholic Bible plus two other Bible resources, Catechism, 1909 Catholic encyclopedia another must, The 1910 Catholic Dictionary, a Catholic Doctrinal Concordance, How Protestants Study the Bible versus how Catholics study the Bible, and  a number of special tools for studying the Bible With Greek and Latin tools for studying the basic Greek Grammer to enhance one's understanding of definitions etc. 

This has become a consolidation of free modules for e-Sword base progam, modules scattered across ensips web, and a few other websites on the internet all to make for easier download and finding of Catholic modules and good study tools.  Michael Jacques

 Note: e-Sword has recently gone to a new version 9.0 as of 4/17/2009 which no longer uses the old MS Access Data base modules, they will work with all older versions of the e-sword program.  I have converted most of modules to the new SQLite data base modules.

A Free Greek English-Hebrew English interlinear Bible which is better than the interlinear for e-Sword is available at http://www.scripture4all.org/

 We need to put word out to our churches, Bible study coordinators, Religious Educators, students, seminarians, for priests material here to help with sermons. etc--of what is available here at their fingertips. Those who are studying and making use of this need to consider now or down line for getting involved in Catholic Religious Ed. This is a work in progress so come on back and see whats new.

I have added some Compiled HTM Linked files for those who have trouble navigating the eSword, a small Catholic Bible Study, and Church fathers.

The following may be helpful for seminary students, religious professor/faculty- teachers, any Catholic students taking  religious education classes,  and also may be of use in helping priests prepare sermons for Gospels readings of the day using Catholic commentaries, and church Fathers quotes, religious Education Directors and CCD Teachers, and of course it may be useful for any Catholic in learning more about their faith, Scripture etc.....  Please be sure to pass this along.
