Although the humanists rejected God and Christianity, classical studies do not necessitate such rejection. The greatest great book of the ancient world is the Holy Bible, and it must be the backbone of all your studies. You and the children need to be more grounded in the Word than in any other book. The other classics can be studied as well, but ONLY if the Word of God is the base and backbone of all you learn:
“Oh how I love Thy law!
It is my meditation all the day.
Thou through Thy commandments hast made me wiser than mine enemies:
For they are ever with me.
I have more understanding than all my teachers:
For Thy testimonies are my meditation.
I understand more than the ancients,
Because I keep Thy precepts.
I have refrained my feet from every evil way,
That I might keep Thy word.
I have not departed from Thy judgments:
For Thou Thyself hast taught me.
How sweet are Thy words unto my taste!
Yea, sweeter than honey to my mouth!
Through Thy precepts I get understanding:
Therefore I hate every false way.”
Psa 119:97-104 (emphasis added)
Notice that someone will have more understanding than all his teachers and all the ancients if God’s testimonies are his daily meditation, and also if God’s precepts are obeyed. We cannot make the same mistake as the 15th century Church, by giving lip service to God’s Word and then living for our own passions.
When the Lord Himself is teaching you and the children, He will guide you into all truth, and you will hate every false way. Intimate knowledge of God’s Word, and love for Him and fear of Him, will guard your heart and mind in Christ Jesus. What you then read in any other book, what is true in it will be apparent to you, as well as what is false.
